For each of the following:
Sketch the scenario. Include as many variables as possible on your sketch (angle, mass, μ).
Create a FBD of the scenario. Include on/by notation for each of the identified forces.
Determine the ΣF / Net Force acting on the block.
Using the given equations, determine the solution to the question.
Block Accelerating w/o Friction
Block Accelerating w/o Friction
A 10 kg block is released from rest on a ramp that makes an angle of 20˚ to the horizontal. If the force of friction between the block and ramp is negligible, determine the acceleration of the block down the ramp.
Block on Ramp at Rest
Block on Ramp at Rest
A 6 kg mass is stationary on a ramp that makes an angle of 30˚to the horizontal. What is the coefficient of static friction between the ramp and block?
Mass on a Ramp Sliding at a Constant Speed
Mass on a Ramp Sliding at a Constant Speed
A 6 kg block is sliding down a ramp, which makes and angle of 30˚to the horizontal, at a constant speed. What is the coefficient of (kinetic) friction between the block and ramp?
Mass on a Ramp with friction and accelerating
Mass on a Ramp with friction and accelerating
A 9kg block is on a ramp which makes an angle of 40˚to the horizontal. If it is released from rest, what is its acceleration? The coefficient of kinetic friction between the block and ramp is 0.2.
