If an 0.6kg apple is dropped from 0.5m height onto a seesaw and flips up a 0.25kg kiwi. to what height does that kiwi reach. assume all the energy of the apple transfers perfectly to the kiwi. show work

keep the tip. ; )

answer

Height at which kiwi reach=1.2m

Solution

In this question we have given

mass of apple,

mass of kiwi,

height from which apple is dropped,

Let the height at which kiwi reached is

here,

We will apply law of conservation of energy

it means,

potential energy of kiwi= potential energy of apple

......(1)

here g is gravitational acceleration

put values of and in equation 1

therefore, Height at which kiwi reach=1.2m
