Two football players with mass 75 kg and 100 kg run directly toward each other with speeds of 6 m/s and 8 m/s respectively. If they grab each other as they collide, the combined speed of the two players just after the collision would be: (Hint: one of the velocity must be negative for the collision to happen.)
2 m/s
3.4 m/s
4.6 m/s
7.1 m/s
Conservation of momentum follows from
Newton’s first law
Newton’s second law
Newton’s third law
the law of conservation of energy
Select the best equation that would help solve the problem:
Ball A and Ball B have the same mass. Ball A rolls and collides with Ball B at rest. Ball A rolls with some velocity after the collision, what is the velocity of Ball B?
Δp = mv
p = mv
(before) mAvA + mBvB = mAvA + mBvB (after)
(before) mAvA + mBvB = (mA + mB)v (after)
Select the best equation that would help solve the problem:
An arrow collides and sticks with a target that is hanging on a string with negligible mass. To find the velocity of the arrow and target after the collision.
Δp = mv
p = mv
(before) mAvA + mBvB = mAvA + mBvB (after)
(before) mAvA + mBvB = (mA + mB)v (after)
A car crashes into a barrier with an impulse of 40,000 kg x m/s. The collision took 2 seconds. How much force did the barrier exert?
80,000 N
60,000 N
40,000 N
20,000 N
What is the total impulse
