A boy uses a slingshot to launch a pebble straight up into the air. The pebble reaches a height of 24.0 m above the launch point 2.3 seconds later. Assume air resistance is negligible.
(a) What was the pebble's initial speed (just after leaving the slingshot)?
(b) How much time did it take for the pebble to first reach a height of 12.0 m above its launch point?
