WHO WANTS BRAINLY?? ANSWER THESE 3 PHYSICS QUESTION!!!
1. What velocity must a car with a mass of 1210 kg have in order to have the same momentum as a pickup truck which has a momentum of 5.6 x 10^4 kg m/s to the east?
2. A 0.50 kg football is thrown with a velocity of 15 m/s to the right. A stationary receiver catches the ball and brings it to rest in 0.020s. What is the force exerted on the receiver?
3. A 0.40 kg soccer ball approaches a player horizontally with a velocity of 18 m/s to the north. The player strikes the ball and cases it to move in the opposite direction with a velocity of 22 m/s. What impulse was delivered to the ball by the player?
1. The car should move with velocity of 46.28 m/s
2. The force exerted on the receiver is 375 N
3. The player delivered an impulse of !.6 N s to the ball
What is Impulse?In Physics, Impulse is the product of mass and change in velocity. from Newtons law change in momentum is equal to impulse
m ( v - u ) = f * t = impulse = momentum
m = mass
v = final velocity
u = initial velocity
f = force
t = time
1.
Given:
mass = 1210 kg
momentum = 5.6 x 10^4 kg m/s
change in velocity = v - u = ?
u = 0 so change in velocity = v
momentum = mass * velocity
velocity = momentum / mass
velocity = 5.6 x 10^4 / 1210
velocity = 46.28 m/s
2.
Given:
m = 0.50 kg
u = 15 m/s
v = 0
t = 0.020 s
m ( v - u ) = f * t
f = 0.50 * ( 0 - 15 ) / 0.02
f = -375 N (the negative sign indicates the direction of the stoppage force as against the force that produces the motion )
force = 375 N
3.
Given:
m = 0.40 kg
u = 18 m/s to the North
v = 22 m/s
m ( v - u ) = impulse
impulse = 0.4 (22 - 18 )
impulse = 1.6 N s

An elevator cabin has a mass of 358.1 ݇݃, and the combined mass of the people inside the cabin is 169.2 ݇݃. The cabin is puled upward by a cable, with a constant acceleration of 4.11 ݉/ݏଶ
. What is the tension in the cable?
Explanation: First fix your units. acceleration is in m/s/s.
T-Mg=Ma
M=348.1+169.2 =517.3 kg
T= 517.3 (9.81+4.11)

How do the displacement, velocity, and acceleration of a runner change as he races from the starting
line toward the finish line along a straight path?
Answer:
maybe line toward the finish
Explanation:that question is confusing
Velocity is the pace at which your displacement is shifting; it describes how quickly and in which direction you are travelling. And acceleration, which is measured in meters per second, is the rate at which your velocity is changing (or meters per second squared).
What factor that affect the acceleration and velocity?Net force and mass are the two primary factors that impact how quickly an item accelerates. For instance, mass has an inverse relationship with acceleration while net force has a direct relationship.
The acceleration is also influenced by other elements like friction, air or fluid resistance, and pressure.
According to the second law, the mass of the item and the net force acting on it both impact how quickly an object accelerates.
Therefore, an object's acceleration is directly proportional to the net force applied on it and inversely proportional to its mass.
