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!!! :(

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
