A student drags a deer he shot across flat ground. The deer has a mass of 75 kg and the coefficient of kinetic friction between the deer and the ground is 0.63. If the student pulls with a horizontal force of 800 N, what is the acceleration of the deer?

Just like Louis, Maria left a book on the roof of her car before driving away. The mass of the book was 725 grams. The coefficient of static friction between the book and the roof was 0.28. The coefficient of kinetic friction between the book and the roof was 0.23. Maria started her car and drove forward on level ground with an acceleration of 3.6 m/s?. As Maria was driving away with that acceleration, what was the magnitude of the force of friction (in newtons) between the book and the roof of the car?

You are pulling a 72-kg box at a constant speed of 7.4 m/s. If you're pulling the rope with a force of 300 N at an angle of 37° measured above the horizontal, what is the coefficient of friction between the box and the ground?

A 1.89 kg brick is sliding down a 28 degree slope.  The coefficient of kinetic friction between the brick and the slope is 0.104.  What is the acceleration downslope of the brick in meters per second squared?

A block with mass 2500g is pulled by a horizontal rope along a horizontal frictionless surface. If the tension in the rope held by the hand is 40 N, what is the acceleration of the block?

A stagehand starts sliding a large piece of stage scenery originally at rest by pulling it horizontally with a force of 159 N. What is the coefficient of static friction between the stage floor and the 317 N piece of scenery?
