A light ball is falling vertically through air. The variation with time t of the resistive force F_R acting on the ball is shown. [graph of F_R against time t, curve rising from origin and levelling off, with t_1 and t_2 marked on the time axis] At which times are the speed of the ball zero, the speed at a maximum and the acceleration zero?

1. Azero speed t_1, maximum speed t_2, zero acceleration t_1
2. Bzero speed t_1, maximum speed t_2, zero acceleration t_2
3. Czero speed t_2, maximum speed t_1, zero acceleration t_1
4. Dzero speed t_2, maximum speed t_1, zero acceleration t_2
