1. A 4kg ball is on a 5m ledge. if it is pushed off the ledge, how much kinetic energy will it have just before hitting the ground? 2. a 3 kg rock sits on a 0.8 meter ledge. how much gravitaional potential energy does it have while it sits on the shelf?

b. what will happen to the gravitaional potential energey if the rock falls off the shelf

c. if it is pushed off, how fast will it be going at the bottom just before it hits the ground?

3. a 0.003 kg fog jumps into the air at 3 m/s. what is the energy of the movement of the frog?

4. as the frog rises in the air he gains (blank) energy and loses (blank) enegry since he slows down.

5. assuming that all of the kinetic energy of teh fog is converted to potential enegery at the top of his jump before he falls back down to the ground, what height would he acheive with this jump?

Whoever answers all five questions will get brainliest and a five star rating/thanks please help me asap this is due tomorrow!!! :(
