Unformatted text preview: ce in the direction, which causes it to move so that its velocity is given by , with in seconds and in m/s. Which is a correct expression for the power in Watts due to the net force, as a function of time? (A) (B) (C) (D) with in Newtons. Thus, in Watts. (g) [4pt] Mass A, traveling to the right at 3.0 m/s, has an elastic collision with a stationary mass B, and bounces back to the left at the 1.0 m/s. What is the speed of mass B after the collision? (A) (C) 1.0 m/s 3.0 m/s (B) (D) 2.0 m/s 4.0 m/s (E) More information is needed to answer. Before: 3.0 m/s A B After: A 1.0 m/s B ? In an elastic collision, the relative speeds are the same before and after the collision. This means that after the collision, m/s. Since m/s, this implies that m/s....
