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
