A 75.65 kg object, initially at rest, is acted upon by a 325.6 Newton force for 4.0 seconds. a. Find the magnitude of the acceleration of the object. b. Find the speed of the object after 4.0 seconds. c. After 4.0 seconds the force is removed and a constant braking force is applied to the object. This braking force causes the object to come to rest after moving 7.50 meters from point at which the braking force is initially applied. Find the magnitude of the braking force.
