Question

a particle moving along the x axis has acceleration f at time t given f=f0(1-t/T)where t and f0 are constant the particle at t=0 har velocity zero when f=0 the particle velocity ls​

Answer 1

Do refer to the above attachment ⤴,

Here we can't use the equation of motion as acceleration is not constant.

In these questions, we use integration as our best tool,

First of all, find the value of c (constant of integration) from the integration,

then find the required time,

and at last, do the integration from t=0 to t=T,

Well, it's a bit lengthy but I'm sure you'll tackle the integration.
