A Problem from Motion

Sandeepan Asked:

“Q. Velocity of a moving particle is given by v = t2 – 4. Find out:-
(i) Time at which velocity is zero.
(ii) Acceleration at which t= 1s
(iii) What type of motion uniform or non-uniform.”

 

Ans:

In the equation, put v=0 to find the time at which velocity equals zero

Differentiate the equation and then put t=1 to find acceleration at t=1s since a = dv/dt

The motion is non uniform as its velocity varies with time.
