A block accelerates at across wood. The coefficient of friction wood is . How much force was applied to the block?

A block accelerates at across concrete. The coefficient of friction of concrete is . How much force was applied to the block?

A force is applied to a block sitting on a sheet of ice. What is the acceleration of the block?

A force is applied to a block causing it to accelerate at across concrete. The friction acts with of force. What is the mass of the block?

A man is rolling a recycling bin of mass down his driveway, which has a slope of , at a constant velocity when he accidentally drops it. What is the total frictional force on the recycling bin if it is decelerating at a rate of ?

Consider the following system:

Two masses, A and B, are attached to the end of a rope that runs through a frictionless pulley.

The two masses are initially held at rest. When they are released, what is the initial instantaneous acceleration of mass A, and in what direction? Neglect air resistance and any frictional forces.

A truck is pulling a trailer and is accelerating at . The truck has mass and the trailer has mass . Determine the force the truck is applying on the trailer. Ignore friction.

Consider the following system:

Two masses, A and B, are attached to the end of a rope that runs through a pulley.

The system is at rest. The pulley has become quit old and has develop a thick coat of rust. If , what range of mass B will result in the system remaining at rest if the static frictional force within the pulley is ?

A truck is pulling a trailer and is accelerating at . The truck has mass and the trailer has mass . Determine the force and direction the trailer is applying on the truck.

John has just finished chopping a bunch of firewood and has to get it in a pile by his house. He elects to use a sled to pull the wood across the gravel road to his house. The road and the sled maintain a coefficient of static friction determined to be . John is able to cram of wood into the sled. After chopping all the wood he is tired but convinced he can move the sled. If John can pull with a max force of can he pull the sled to his house and if not how many newtons of force is he short?
