Question

A plate with a mass of 0.375 kg is dropped and has a speed of 3 m/s when it suddenly hits the
hard kitchen floor. Calculate the change in momentum. (Note: the final speed of the plate is,
of course, zero when it hits the floor.)

Information: Changing Momentum As Newton's 1" Law states, an object's velocity will not change unless a force acts on the object. Since momentum involves velocity, a force will change an object's momentum. The force that causes a change in momentum is called an impulse. An impulse may be a very quick push or a push that lasts for a long time. To calculate how much the momentum changes you need to know how long the force lasts. "A" means “change in" Ft = m(Av) Impulse Force Change in momentum F= force of impact in Newtons m = mass of the object in kg t= the time of impact, how long the impact force acts on the object Av = change in velocity of the object Before proceeding to the questions, please notice the difference between "force of impact" and "impulse force". The impulse force is actually the force of impact multiplied by the time of impact.
