  1. Friction and Tension Practice Problems

  2. A huge pile of leaves was wrapped in a tarp in the middle of a lawn. The wrapped leaves weigh 580 newtons. The coefficient of friction for the lawn is 0.55. How much force is required to start sliding the wrapped leaves?

  3. The plastic wading pool weighs 50 newtons. But the water in it weighs 4,000 newtons. How much force is required to slide the filled pool if the coefficient of friction is 0.22?

  4. At an applied force of 530 newtons, the boulder just began to slide. Assuming a coefficient of friction of 0.65, how much did the boulder weigh?

  5. If a 50kg desk is in motion, what force must be used to keep it moving at a constant velocity if the coefficient of kinetic friction is 0.52?

  6. Edwardo applies a 4.25-N rightward force to a 0.765-kg book to accelerate it across a tabletop. The coefficient of friction between the book and the tabletop is 0.410. Determine the acceleration of the book

  7. In a physics lab, Kate and Rob use a hanging mass and pulley system to exert a 2.45 N rightward force on a 0.500-kg cart to accelerate it across a low-friction track. If the total resistance force to the motion of the cart is 0.72 N, then what is the cart's acceleration?

  8. A 6.58 x 103 N upward tension force is exerted on a 521-kg downward-moving freight elevator. Determine the acceleration of the elevator.

  9. Elevator and its load have a combined mass of 1600 kg. Find the tension in the supporting cable when the elevator, originally moving downward at 12 m/s, is brought to rest with constant acceleration in a distance of 42 m.
