A) A 2 kg box sits on a ramp of 14 degrees where thecoefficient of friction is 0.4. A 26 N force pulls the box uphill.Find the acceleration.

B) A 3 kg box sits on a ramp where the coefficient offriction is 0.3. Find the angle that will cause the box to slidedownhill at constant velocity.

C) A 3 kg box sits on a ramp of 14 degrees where the coefficientof friction is 0.4. A string runs uphill over a pulley and backdown to a hanging mass of 9 kg. Assuming the box on the rampis pulled uphill by the weight of the hanging mass, find theacceleration.
