 Chapter 3. Dynamics: Inclined Plane

Problem 1. Find an acceleration of a block on an inclined plane of angle . The coefficient of kinetic friction between the block and the plane is 0.2.

Problem 2. A block of mass 2 kg is pushed up by a horizontal force of magnitude 40 N. The block is on an frictionless inclined plane of angle . Find the acceleration of the block.

Problem 3. A block of mass 5 kg is pushed up by a horizontal force of magnitude 60 N. The block is on an inclined plane of angle . The coefficient of kinetic friction between the block and the inclined plane is 0.1. Find the acceleration of the block.

Problem 4.A block of mass 5 kg is released from the rest at the top of an inclined plane of angle . The inclined plane has a length of 50 cm and is frictionless. How long does it take the block to slide to the bottom of the incline?

Problem 5. A block of mass 2 kg is released from the rest at the top of an inclined plane of angle . The inclined plane has a length of 80 cm. The coefficient of kinetic friction between the block and the plane is 0.1. What is the velocity of the block at the bottom of the incline?

Problem 6. A block of mass 1 kg is moving up with initial velocity 5 m/s along an infinite inclined plane of angle . The coefficient of kinetic friction between the block and the plane is 0.2. How long does it take the block to reach the maximum height.

Problem 7. A block of mass 10 kg is standing on an inclined plane of angle . The coefficients of static and kinetic friction between the block and the incline are 0.2 and 0.1, respectively. A boy is trying to push the block up the plane. Find the minimum force he need to apply to move the block. Then the boy continues to push the block with this force. What is an acceleration of the block?
