Question

Given the position function s(t), s(t) = t^3 - 5t, where s is measured in meters and t is in seconds, find the velocity and acceleration of the particle at t = 3 seconds.

Answer 1

velocity = first derivative
acceleration = second derivative

Answer 2

v= 3t^2-5
a= 6t

Answer 3

22 m/sec , 18m/sec^2

Answer 4
