A net force of 50 N causes a mass to accelerate at a rate of 6.8 m/s2. Determine the mass. 

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

Ben (55kg) is standing on very slippery ice when junior (25kg) bumps into him. junior was moving at a speed of 8 m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision. give the answer in m/s. describe the work you did to get the answer.
