The velocity of an object at any point is equal to the rate of change of its displacement at that point. Suppose that an object travels in a straight line and its displacement s mm at time t s is given by s = 8t^4 + 2t^2 + 5. What is the velocity of the object when t = 7? Give your answer in mm s-1 to the nearest integer. The velocity is mm s-1

The velocity of an object at any point is equal to the rate of change of its displacement at that point. Suppose that an object travels in a straight line and its displacement s mm at time t s is given by s=4t^4+3t^3+7 What is the velocity of the object when t=3? Give your answer in mm s-1 to the nearest integer.

The displacement (in meters) of a particle moving in a straight line is given by the equation of motion s = (8)/(t^2) where t is measured in seconds. Find the velocity (in m/s) of the particle at times t = a, t = 1, t = 2, and t = 3. t = a
