Expert Answer

Step 1

To know the values like initial kinetic energy or the gravitational potential energy.

Analyse the motion of the go cart.

Step 2

As initially go cart is at rest, there is no kinetic energy present, but as it is on a height, it has gravitational potential energy.

When the...
