a steel ball, starting from rest rolls down one slope and up another. it takes 2.5s to reach the bottom of the first slope, at which point its speed is 5.0 m/s. if the magnitutde of the acceleration on the second slope is exactly one-half that on the first slope, how long will it take for the ball to come to a stop on the second slope?

The key is to get a value of the acceleration on the first slope. You should be able to get that by using the values given in

v=at

where v is the final velocity, a is the acceleration and t is the time.
