Question
a particle is moving along x-axis has acceleration f at time t given by f=f'[1-(t/T)] , where f' and T are constant. the particle at t=0 has zero velocity. in the time interval between t=0 and the instant where f=0, the particle's velocity (v) is:
(1) [1/2]f'T^2
(2) [1/2]f'T
(3) f'T^2
(4) f'T
