time (in seconds). Find a formula for 1, if V = 5t(t Suppose that an object's acceleration function is given by a = 4t+ 6. The object's initial velocity is 4, and the initi position is 9. Find the object's displacement as a function of time. he acceleration of an object for which the displacements (in m) is given as a function of the time t (in s) for the alue of t.
