Question

The position x (in metre) of a particle along a straight line is given as x = 3t2 – 18t. the maximum speed in the time interval t = 0 to t = 2 s is

Answer 1

Answer:

Explanation: speed will be zero at 3 sec but the initial velocity of the particle is 18m/s ...so at 2 sec some speed may be decrease.. But question is Max speed that will be 18m/s
