Question

A body moves along a straight line and its acceleration at which varies with time t is given by a=2-3t

Answer 1

so by intigrating it we will get velocity as a function of time , and again intigrating it will give you displacement as a function of time
. I hope you know how to integrate a function.

v=(2t) - (3/2)(t^2) + C
s=(t^2) - (1/2)(t^3) + C

you can find the value of C respectively by putting some value of v , s ,t
