A boy sliding down a hill accelerates at 1.40 m/s2. What distance would he slide if he starts by running with an initial velocity of 2 m/s, then he jumps on his sled and slides for 5 seconds.
--------------
His terminal speed is 2 + 5*1.4 = 9 m/sec
His start speed is 2 m/sec
The average speed is (2+9)/2 = 5.5 m/sec
---
5*5.5 = 27.5 meters
