Question

The particle starts from rest and moves along a straight with the acceleration a = 3(1 - t/2) m/s^2. Find the displacement after it moves 2 seconds.


By using application of calculus (integral and derivative )

Answer 1

a=3(1-t/2) m/s²

v=3(t-t²/4) m/s

x=3(t²/2 - t³/12) m

put t= 2 in the above equation

Ans 4m
