A particle moving along the x-axis has acceleration f, at time t, given by f=f0 ( 1 − t T ) 1-tT, where f0 and T are constants. The particle at t=0 has zero velocity. In the time interval between t = 0 and the instant when f = 0, the particle’s velocity (vx) is: 1. f 0 T f0T 2. 1 2 f 0 T 2 12f0T2 3. f 0 T 2 f0T2 4. 1 2 f 0 T 12f0T

A particle moving along the x-axis has acceleration f, at time t, given by f=f0$\left(1-\frac{t}{T}\right)$, where f0 and T are constants. The particle at t=0 has zero velocity. In the time interval between t = 0 and the instant when f = 0, the particle’s velocity (vx) is:

1. $f_{0}T$

2. $\frac{1}{2}{f}_0{T}^2$

3. $f_0{T}^2$

4. $\frac{1}{2}{f}_{0}T$
