If two objects collide and one is initially at rest, is it possible for both to be at rest after the collision? Is it possible for one to be at rest after the collision? Explain. 10) You are standing perfectly still, and then you take a step forward. Before the step, your momentum was zero, but afterward, you have some momentum. Is the principle of conservation of momentum violated in this case?

Two spheres, each of mass m, can slide freely on a frictionless, horizontal surface. Sphere A is moving at a speed v0 = 16 ft/s when it strikes sphere B which is at rest, and the impact causes sphere B to break into two pieces, each of mass m/2.a) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the velocity of sphere A after the collision.b) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the angle θ and the speeds of the two pieces after the collision.
If you are flying in a large airplane in quiet air, and a friend across the aisle tosses you her hand sanitizer bottle, what is the direction of the momentum of the bottle as you see it. Toward your friend, plus some downward motion due to gravitational acceleration Toward the front of the plane due to the plane's velocity None. Momentum does not have direction, only magnitude. Toward yourself, and a little downward because of gravitational acceleration downward
A man claims he can safely hold on to a 10.20 kg child in a head-on collision with a relative speed of 123. mi/h lasting for 0.140 s as long as he has his seat belt on. Hint: 1 mi/h = 0.447 m/s (a) Find the magnitude of the momentum of the child. A man claims he can safely hold on to a 10.20 kg child in a head-on collision with a relative speed of 123. mi/h lasting for 0.140 s as long as he has his seat belt on. (c) For comparison, calculate the magnitude of force generated by the record weightlifting champion in the 2004 Olympics. He lifted 263 kg. Based on these results, is the man’s claim valid?
