The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.
Problem
In Active Example 13.1, the acceleration (in m/s2) of point P relative to point O is given as a function of time by a = 3t2. Suppose that at t = 0 the position and velocity of P are s = 5 m and v = 2 m/s. Determine the position and velocity of Pat t = 4s.
