|
When you jump on a trampoline, you have the most kinetic energy at
|
|
before the jump
|
|
|
the top of the jump
|
|
|
when you first get on
|
|
|
at the bottom of the jump
|
Explanation:
Detailed explanation-1: -Your kinetic energy is greatest, just before you hit the trampoline on the way down and when you leave the trampoline surface on the way up. But your kinetic energy is 0 when you reach the height of your jump and begin to descend and when are on the trampoline, about to propel upward.
Detailed explanation-2: -Since kinetic energy is at a maximum when velocity is at a maximum, we can conclude that kinetic energy is greatest at the top of the hill.
Detailed explanation-3: -At the top of the incline, the mass is still at rest, so the Mechanical energy . At the bottom of the incline, the gravitational potential energy, would be all converted to kinetic energy, , where the object has attained its maximum speed.
