A 2.50 kg mass is released from rest while on and incline of 54.7 degrees. If the coefficient of kinetic friction is 0.529, what is the magnitude of the acceleration of the mass?

If a 3kg box is moving down a ramp with ramp angle 15° and a friction coefficient μk of 0.4, what is the magnitude of the force of friction on the box (in N)?

A block of mass 11 kg lies on a horizontal plane. A force F that is inclined 42.3° with the horizontal is applied to the block (pulled the block) causing it to move 15 meters in 5 seconds. If the coefficient of friction between the block and the horizontal surface is 0.3, find the magnitude (N) of the force F. Round off only on the final answer expressed in 3 decimal places.

A student of mass 61.4 kg, starting at rest, slides down a slide 22.2 m long, tilted at an angle of 28.1° with respect to the horizontal. If the coefficient of kinetic friction between the student and the slide is 0.118, find the force of kinetic friction, the acceleration, and the speed she is traveling when she reaches the bottom of the slide. (Enter the magnitudes.) HINT (a) the force of kinetic friction (in N) N (b) the acceleration (in m/s) m/s? (c) the speed she is traveling (in m/s) m/s Need Help? Read It Watch
