Part 2 After reaching the top of the incline, the box of mass 1 kg is released, and allowed to slide back down the hill of incline angle 0 20 At the halfway point, the surface of the incline becomes rough, and friction becomes important The coefficients of friction between the box and hill are μ-: 0.7 and μ.-0.5. 0 20 D. Draw a free body diagram for the object as it moves down the incline as it encounters the...
A 25.0-kg box is released at the top of a frictionless ramp that is inclined at an angle of 35.0◦ with the horizontal. The box slides 1.50 m down the ramp before you catch it and bring it to a stop in 0.400 m. Assuming you pushed on the box with a constant force that was parallel to the ramp as you caught it, what was the magnitude of the force you exerted on the box to bring it to...
