A student is dragging a 23.7 kg toboggan filled with books up a snowy hill using a light rope aligned parallel to the hill. The hill is sloped at an angle of 26.0˚ from the horizontal. The coefficient of kinetic friction between the toboggan and snow is 0.350.

A 1000-N crate is being pushed across a level floor at a constant speed by a force of 300N at an angle of 20.0o below the horizontal. What is the coefficient of kinetic friction between the crate and the floor?

You want to use a rope to pull a 12 kg box of books up a plane inclined 30 degrees above the horizontal. The coefficient of kinetic friction is 0.28.The rope pulls parallel to the incline. What force do you need to exert on the rope if you want to pull the box with a constant acceleration of 0.50 m/s squared yp the plane?

A 9.61kg box on a ramp with an incline of 26.36° slips, giving it an acceleration of 0.31m/s2. What is the coefficient of kinetic friction between the box and the ramp?

A 15.0 kg box is being pulled along level ground by a 75.0 N force that is directed at an angle of 20o above the horizontal. The coefficient of kinetic friction is 0.330. What is the acceleration of the box?

A box weighing 5kg is pulled along a level floor at constant speed by a rope that makes an angle os 30 degrees with the floor.If hte force applied on the rope is 10N, what is the coefficient of sliding friction between the box and the floor.

Timmy is done placing his things in a big box and ready to transfer to his new condo unit. The movers arrived and uses a wooden ramp with an elevation of 24.6° from the horizontal to load his things to the truck. If the box has a mass of 45.7kg and has a value of coefficient static friction is 0.936. How much force is required for the delivery man to overcome the static friction? O 568.16 N O 385.14 N O 381.54 N O No answer O 586.16 N

A 0.85 kg block of wood is stationary on an incline that is15◦above horizontal. A force of 3.0 N is being applied toit 75◦below horizontal, directly into the incline (the force isperpendicular to the incline). What is the minimum coefficientof static friction required to keep the block stationary?

You are entering the bungee-jumping business and must design the bungee cord. The jump will be from a bridge that is 100.0 m above a river. The design calls for 2.00 seconds of free fall before the cord begins to slow the fall, and the person just touches the water after jumping. Find the force con- stant and length of the bungee cord for a 100.0 kg person.

A 50.0kg object is pushed across a level surface with a diagonal force of 550 N causing it to move forward at a constant velocity of 6.00 m/s. Calculate the coefficient of kinetic friction. Can you please write it instead.
