3.) An 80kg box is being lowered down a ramp with a 15 degree incline. The coefficient of static friction between the box and the ramp is .25. a) What is the Normal force the ramp applies to the box? b) What is the force due to friction on the box? c) What is the Force up the ramp required to keep the box at constant velocity?
A 3.00-kg block is moved up a 37-degree incline by a constant horizontal force of 40.0 N. The coefficient of kinetic friction is 0.10, and the block is displaced 2.00 m up the incline. Note: The applied force is not parallel to the incline. Calculate the work done by gravity and the work done by friction.
Two masses are being pulled up a 30.0 degree incline by a force F parallel to the incline. The acceleration down the incline is 1.00 m/s2 and the velocity is up the incline. The force is applied to a 200 kg mass, and a string connects the 200 kg mass to a 150 kg mass. The coefficient of kinetic friction is 0.200. What is the tension in the string? answer: 840 N
