20.0-kg block initially sits at rest on a rough horizontal
floor. One end of a string is attached to the block. You pull on
the other end of the string with a force of 40.0 N so that the
string makes an angle of 30.0° with the horizontal. After pulling
the block 3.00 m across the floor, it is traveling with a speed of
1.25 m/s. What is the magnitude of the force of kinetic friction
exerted on the block...

A 8.0kg block is pulled along a horizontal frictionless floor

7.00 kg block sits on the floor at rest. Block is being pulled
across a frictionless floor with a force F=14 N at an angle of 35
degrees. What is the magnitude of block’s acceleration?

A 12 kg block is pulled along a level plane by a F = 76 N force
directed 40° above the horizontal. The coefficient of kinetic
friction between the block and plane is 0.39. Find the x-component

76 N force acting on the block. Find the normal force acting on the
block. Find the friction force acting on the block. Find the
acceleration of the block.

A mass m = 13 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.07, for a
distance d = 5.1 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 33° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 33°
(thus on the incline it is...
