For Q5 (iii) The difference in height taken is (2.45-1.2)= 1.25 metre. Because this is a smooth surface we dont have to get confused between the change when travelling from N to M. So Loss (K.E) = Gain (P.E)
Put the height to get the potential energy and calculate the velocity from the lost kinetic energy.
