Work done on an Object along a **Rough** Inclined Plane A crate **of mass** 10kg is **pulled up** a **rough incline** plane with an initial speed of 1.5m/s. The pulling force is 100N parallel to the **incline**, which makes an angle of 20° with the horizontal. The coefficient of. **The** above box of **mass** 29 kg is being **pulled** **up** **a** frictionless **incline**, with an applied force of 370 N, which makes an angle of 420with the horizontal. **a**) Draw the free body diagram showing all forces. b) Resolve the gravitational force into its x and y components along the rotated coordinate system. c) Find the value of the Normal force.
