Question:

A body moves in a straight line so that, ts after passing through a fixed-point O, its displacement from O is s m. The velocity O is sm. The velocity v ms^-1 is such that v = 5 cos 4t.

a. Write down the velocity of the body as it passes through O.

b. Find the value of t when the acceleration of the body is first equal to 10 ms^-2.

c. Find the value of s when t = 5.
