A professional diver of mass `60kg` performs a dive from a platform `10m` above the water surface. Find the magnitude of the average impact force experienced by him if the impact time is `1s` on collision with water surface. Assume that the velocity of the diver just after enering the water surface is `4ms^(-1)(g =10 ms^(-2))` .
