(e) As the boat passes over a wave, the gravitational potential energy of the boat increases by 19600 J. mass of boat=8000kg gravitational field strength=9.8N/kg Calculate the change in height of the centre of mass of the boat as it passes ov the wave.

## Step 1: We are given the increase in gravitational potential energy ( ) as , the mass of the boat ( ) as , and the gravitational field strength ( ) as . We are asked to find the change in height ( ) of the center of mass of the boat.## Step 2: We can use the formula for gravitational potential energy to find the change in height. The formula is:### ## Step 3: Rearrange the formula to solve for :### ## Step 4: Substitute the given values into the formula:### ## Step 5: Calculate the quotient to get the change in height:### ###
