The distance d of a particle moving in a straight line is given by d(t) = 2t^3 + 5t – 2, where t is given in seconds and d is measured in meters.

Find the velocity of the particle for t = 7 seconds.

A) 152 m/s

B) 47 m/s

C) 733 m/s

D) 299 m/s

The derivative of the position function gives the velocity function

2 t^3 + 5 t -2    derivative   =   6 t^2 + 5
