Problem

An object moves with constant acceleration starting with velocity v0=5.00v_0 = 5.00 ms\frac{m}{s} and ending with a velocity of v=−1.00v = -1.00 ms\frac{m}{s} in a time of 3.003.00 ss. For this motion, what is the average speed associated with the object? (A) 2.002.00 m/sm/s (B) 2.172.17 m/sm/s (C) 2.502.50 m/sm/s (D) 2.832.83 m/sm/s (E) 3.003.00 m/sm/s
