IB Mathematics HL – Calculus, Application of Differentiation, Kinematics

Can someone help me with the following exercise?

“A particle moving in a straight line has its displacement given by the following equation



a) find the particle’s velocity and acceleration at time t
b) find the time when the particle come to rest. ”


Thanks
Max

IB Maths HL– Calculus, Application of Differentiation, Kinematics


a) Since the velocity (v) is the first derivative of the displacement function, we have





Since the acceleration (a) is the first derivative of the velocity function found above, we have





b) The particle come to rest when velocity equals to zero




Hope these help!! :D :D
