1. A block is resting at the left end of a 12 meter long ramp. The left end can be raised with a jacking system, while the right end remains on the level wooden surface. Coefficients of friction for the ramp are: Static 0.50, Kinetic 0.40. The left end of the ramp is raised just enough to cause the block to start to slide.

a) How high was it raised?

b) What is the speed of the block when it reaches the right end of the ramp?

c) Coefficient of kinetic friction on the wooden floor is 0.25. How far does the block slide on the floor?

A 20-kilogram box ¼-meter long is located at the center of a 5-meter long ramp that is inclined at 45 degrees above horizontal. A pulley is at the ramp’s upper end and a light weight string runs from the box up and over the pulley connecting to a temporarily supported 5-kilogram mass below the pulley coefficient of static friction (μs) between the block and the ramp is 0.50 and the coefficient of kinetic friction (μk) is 0.40. a. If the...

A 50-kilogram box is pushed up a 10.0-meter long ramp. The high end of the ramp is elevated 6.0 meters above the low end (the ramp forms a 3-4-5 triangle). While moving the 10 meters up the ramp the box accelerates from 0.0 meters per second to 2.0 meters per second. a. How much work against inertia was performed; b. How much work against gravity was performed; and c. If the coefficient of kinetic friction (μK) was 0.25, how much...

2.A 5 kg wooden block sits on a flat straight-away 12 meters from the bottom of an infinitely long ramp, which has an angle of 20 degrees. The straightaway has a coefficient of kinetic friction of 0.4 and the ramp of 0.25. While the block is on the flat section, you exert a 100 N force at an angle of 45 degrees above the horizontal, propelling the block towards the ramp. a.What is the velocity of the block right before...
