Thanxs.. did I set this one up right?
A Metal sphere with a mass of 40kg rolls along a frictionless surface at 40m/s and strikes a stationary sphere having a mass of 400kg. The firsts sphere stops completely. At what speed does the second sphere move away from the point of impact...
I need help on these 2 questions.
1) What impulse if needed to stop a 100kg mass traveling at a velocity of -25m/s?
and
3) A force with a magnitude of 430 N is used to stop an object with a mass of 45kg moving at a velocity of 900m/s. How long will it take to bring the object to a full...
