Two blocks of equal mass (10 kg) are on a horizontal, frictionless surface. Block A is moving toward Block B, which is at rest, with a speed of 2 m/s. a. If the blocks remain together after collision, what is their velocity? b. If Block A is stopped in 0.1 s, what is the average force acting on Block B?

Follow-up Question

The answer for part b that I have says 200N. I just was not sure how to do it. Should you be using 2 m/s ( Block A) as the velocity in this equation, instead of 1 m/s?  Thanks.
