Recall that Newton's law says that F 2 ma, where F is force, an is mass, and a is acceleration. 2 Suppose now that for a certain object moving along a straight line =2 meters per second per second. Suppose also that the object is 2 meters to the right of a reference point at time 0 seconds, moving to the left at 1 meter per second. (a) By setting up and solving an appropriate initial value problem, nd expressions for 3(t) and 3'05), the position and velocity of the object at time 15 respectively
