A physics student monitors the speed and kinetic energy of a 0.32-kg traveling object. At a time of t = 1.0 s, the object is traveling with a speed of 4.5 m/s and at a time of t = 4.0 s, the object has a kinetic energy of 27 J. Determine the following. (a) kinetic energy of the object at t = 1.0 s (b) speed of the object at t = 4.0s
