Problem
An object moving only to the right completes a second trip in two stages, I and II. The average speed of the entire second trip is v m/s.
For stage I, the object moves with a constant velocity of v1 m/s for t1 seconds.
What constant acceleration must the object have during the t2 seconds of stage II?
(A) a1 m/s² (B) a2 m/s² (C) a3 m/s² (D) a4 m/s² (E) a5 m/s²
