Question

Q5 Displacement(y) of the particle is given by y=2t+t 2 −2t 3 the velocity of the particle when acceleration is zero is given by a. 5/2 b. 9/4 c. 13/6 d. 17/8

Answer 1

Hope the pic i attached below helps you!!

THE WHOLE CONCEPT OF THIS QUESTION LIES IN FINDING THE VALUE OF TIME AT WHICH THE ACCELERATION BECOMES ZERO, AND THEN PUT THE VALUE OF TIME IN THE EQUATION FOR VELOCITY.

ANS IS OPTION C) 13/6 m/s
