Asked by Nat

A boy uses a slingshot to launch a pebble straight up into the air. The pebble reaches a height of 29.0 m above the launch point 3.3 seconds later. Assume air resistance is negligible.

b) How much time did it take for the pebble to first reach a height of 14.5 m above its launch point?
