2. Roger Federer hits a tennis ball of mass 0.05kg directly upwards in the air at a velocity of 25 m/s.
a) Calculate the initial KE of the tennis ball. (3)
b) What therefore is the maximum GPE of the tennis ball? (1)
(assume no energy is dissipated to the surroundings)
c) Calculate the maximum height that the tennis ball reaches? Assume gravitational field strength is 9.N/kg.
