How fast must a 100 kg object be going in order for it to stop a 200 kg object traveling at 10 km/hr when the two objects collide head on?

An object has a mass of 13.5 kilograms. What force is required to accelerate it to a rate of 9.5 m/s2?

What is the relationship between Newton's second law and gravitational acceleration?

What are two main purposes for using repetition when conducting experiments?

During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of 2.60 m/s, grabs and holds onto him so that they move off together with a velocity of 1.30 m/s.

What effect does an increase in temperature have on viscosity?

Aman tosses a jart upward with a velocity of 14.1 m/s a 60° angle
