Question

Find the velocity of an object at t=1, given that the displacement for the object moving along a straight line is given by s= ((1/14)t^3-(1/14)t^2))

Answer 1

You have s(t), the displacement function. The velocity function should be v(t) = ds/dt. Can you find the first derivative of that s(t)?

Answer 2

The derivitive would be (3t^2-2t)/(14)

Answer 3

Where do I go from here? Do I enter t=1 into the t variable in the derivative equations?

Answer 4

Hi?

Answer 5

That's it. Substitute t = 1. Done.
