Question

Position time equation for a particle is x = 2t^3 - 6t^2
Maximum speed will be
(1) 6 m/s
(2) 12 m/s
(3) 18 m/s
(4) 3 m/s​

Answer 1

Answer:

6 m/s is the correct answer

firstly double differentiate the equation and put it equal to zero and you will get the value of t

now put the value of time in equation of velocity and you will get the maximum velocity
