1)A 1 kg brick is carried to up the Eiffel Tower to the 275 m platform. How
much gravitational potential energy does it acquire?
Answers
Answer:
The gravitational potential energy is 2,750 Joules
Explanation:
Given the following data;
Mass of brick = 1kg
Height of Eiffel Tower = 275m
Potential energy can be defined as the energy possessed by an object due to its position.
Mathematically, potential energy is;
[tex] P = mgh[/tex]
Also, we know acceleration due to gravity = 10m/s2
[tex] P = mgh[/tex]
[tex] P = 1 * 275 * 10 [/tex]
P = 2750 Joules.
Hence, the gravitational potential energy the brick acquired is 2750 Joules.

The fastest human ever recorded was Usain Bolt at 43 km/h. If a white tail
deer can run 3 km in 3 minutes and 45 seconds, how many km/h faster would Usain Bolt need to run to catch a deer?
Please show work! Will mark brainliest!
Answers
Deer 3km/3.75min because 45sec/60sec = .75min
All we need to do is convert
3km/3.75min * 60min/1h = 48km/h
Usain bolt 43km/h - deer 48km/h

mechanical advantage of a simple machine is 4,what does it mean?
Answers
Answer:
I hope this answer is correct
Explanation:
The mechanical advantage of a machine is 4. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
HeLp AsAp!!!!!! How long would it take you to hop 30 meters based on your speed for the 5-meter trial? Show your work!
Hopping =
Distance-5 m
Time-3.41
Speed-1.46
Answers
Answer:
20.5s
Explanation:
Given parameters:
Distance = 30m
Unknown:
Time = ?
Solution:
The time it will take to hop a distance of 30m using the speed for the 5m trial is the duration of the trip.
The speed for the 5m trial = 1.46m/s
Now;
Speed = [tex]\frac{distance}{time}[/tex]
Distance = speed x time
time = [tex]\frac{distance }{speed}[/tex]
Input the parameters and solve;
time = [tex]\frac{30}{1.46}[/tex] = 20.5s

A vertical rope is attached to an object that has a mass of 40.0 kg and is at rest.
The tension in the rope needed to give the object an upward speed of 3.50 m/s
in 0.700 s is
Answers
Answer:
239.2 N
Explanation:
Given that a vertical rope is attached to an object that has a mass of 40.0 kg and is at rest.The tension in the rope needed to give the object an upward speed of 3.50 m/s
in 0.700 s is
The tension in the rope and the weight of the mass will be acting in an opposite direction.
T - mg = ma ....... (1)
Where acceleration a = Velocity/ time
a = 3.5 / 0.7
a = 5 m/s^2
Substitutes acceleration a into the equation 1 above.
T - 40 × 9.8 = 40 × 5
T - 39.2 = 200
T = 200 + 39.2
T = 239.2N
Therefore, the tension in the rope needed to give the object an upward speed of 3.50 m/s
in 0.700 s is 239.2N
Answer:
The answer is T=592 N
Explanation:
Fw= 392N
a=v/t, so a=3.5ms^-1/0.7s
a=5ms^-2
Fnet=ma
T-Fw=ma
T-392N=40kg(5ms^-2)
T=592N
Which of the following are examples of acceleration?
A. A car speeds up after getting on a highway.
B. A car travels at a constant velocity on a highway.
C. A car slows down to exit a highway.
D. A car rounds a sharp curve on an off ramp at a constant speed.

Together, Denise and her brother painted a total of 3 5 of a living room wall. Denise painted 3 5 of that part, and her brother painted the rest. What part of the living room wall did Denise paint herself? Denise paintedof the living room wall.
Answers
Answer:
9 ÷ 25
Explanation:
The computation of the part of the living room that should be painted is shown below:
= Living room painted × rest of the part painted
= 3 ÷ 5 × 3 ÷ 5
= 9 ÷ 25
We simply multiplied with the above two items and the same is to be considered
hence, the part of the living room i.e. painted is 9 ÷ 25

Ben has two carts with masses of 0.1 kg and 0.2 kg. He pushes the smaller cart toward the larger cart and they collide. The smaller cart rebounds back in the direction it came from. He measures the force on the smaller cart from the larger cart to be 5 N. What was the magnitude of the acceleration of the smaller cart?
Answers
Answer:
The acceleration of the smaller cart is 50 m/s²
Explanation:
The given masses of the carts are 0.1 kg and 0.2 kg
The direction in which the small cart bounces = In the revers to its initial direction
The force exerted by the larger cart on the small cart = 5 N
Therefore, we have;
Force acting on smaller cart = Mass of smaller cart × Acceleration of the smaller cart
∴ The acceleration of the smaller cart = Force acting on smaller cart/(Mass of smaller cart)
The acceleration of the smaller cart = 5 N/(0.1 kg) = 50 m/s²
The acceleration of the smaller cart = 50 m/s².

how much force is needed to accelerate 300 kg at a rate of 4 m/s/s
Answers
Answer:
1200
Explanation:
Force = Mass x Acceleration
Answer:
[tex]\boxed {\tt 1,200 \ Newtons }[/tex]
Explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F=m*a[/tex]
The mass is 300 kilograms.
The acceleration is 4 meters per second squared.
[tex]m= 300 \ kg\\a= 4 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 300 \ kg * 4 \ m/s^2[/tex]
Multiply.
[tex]F= 1200 \ kg * m/s^2[/tex]
1 Newton is equal to 1 kilograms meters per second squared, so our current answer of 1200 kg m/s² is equal to 1200 Newtons.
[tex]F= 1200 \ N[/tex]
The force needed is 1,200 Newtons.
