Linear Momentum
A red ball with a velocity of +3.0 m/s collides head-on with a yellow ball of equal mass moving with a velocity of -2.0 m/s. What is the velocity of the yellow ball after the collision?
+5.0 m/s.
+3.0 m/s.
Zero.
-2.0 m/s.
Two objects collide and stick together. Kinetic energy:
Is definitely conserved.
Is conserved only if the collision is elastic.
Is conserved only if the environment is frictionless.
Is definitely not conserved.
What is the SI unit of momentum?
N/m
Ns.
Nm.
N/s
Two cars collide head-on on a level friction-free road. The collision was completely inelastic and both cars quickly came to rest during the collision. What is true about the velocity of this system's center of mass?
None is correct.
It was not zero, but ended up zero.
It was always zero.
It was never zero.
Which of the following is an accurate statement?
If the kinetic energy of an object is doubled, its momentum will also double.
The momentum of a projectile is constant.
If an object is acted on by a non-zero net external force, its momentum will not remain constant.
The momentum of a moving object is constant.
