Question

a particle moving along x-axis has acceleration f, at time t, given f = where f, and t are wconstants. the particle at t = 0 has zero velocity. when f = 0, the particle's velocity (vx) is

Answer 1

Answer:

Instantaneous velocity at the instant when t = 0, a = ao(1 - t/T), When a = 0, t = T, a = ao(1 - t/T), dv/dt = ao(1 - t/T), dv = ao(1 - t/T) dt,

Integrate, v = ao(t - t²/(2T)), When t = T (i.e when a = 0), v = ao(T - T²/(2T)), v = ao(T/2). Therefore, velocity at the instant when a = 0 is = ao(T/2)

Answer 2

Explanation:

Instantaneous velocity

t = 0

a not ( 1 - t/T)

if a = 0

t = t

dv/dt = a not ( 1 - t/T)
