a block of mass m = 10.2 kg sitting on a ramp that makes an angle θ = 21° with the horizontal. This block is being pushed by a horizontal force F = 212 N. The coefficient of kinetic friction between the two surfaces is μ = 0.49. Write an equation for the acceleration of the block up the ramp using variables from the problem statement together with g for the acceleration due to gravity. Find the acceleration of the block up the ramp in m/s2.
To understand kinetic and static friction.
A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is μs. The coefficient of kinetic friction is μk, with μk<μs.
Suppose you push horizontally with precisely enough force to make the block start to move, and you continue to apply the same amount of force even after it starts moving. Find the acceleration aaa of the block after it begins to move.
Express your answer in terms of some or all of the variables μs, μk, and m, as well as the free-fall acceleration g.
A horizontal force of magnitude F = 57.5 N pushes on a block of mass m = 4.7 kg. The block is on a frictionless incline that makes and angle θ = 36.1 degrees with horizontal.
Write an expression for the acceleration ax of the block, taking up the ramp to be the positive x direction. Express your answer in terms of F, m, θ, and g (9.80 m/s2).
