A skier slides straight down an incline of 25 degrees without using her poles. The slope itself is 96 meters long, and the skier starts from rest at the top. What would the velocity of the skier be at the bottom of the incline if friction can be neglected? What would your answer be to the previous question if the coefficient of kinetic friction between the skis and the snow is 0.13 on the incline? Upon reaching the bottom of the incline in part b, she reaches a flat portion, and decides to just let friction slow her to a stop. How far does the skier travel along the horizontal portion before coming to a stop, if the coefficient of kinetic friction is 0.28 on the flat portion?
Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?
A crate with a mass of 155 kg, starting from rest, slides down a ramp making an angle of 32 degrees with respect to horizontal. The ramp is 6 meters long. A constant frictional force of 200 N acts throughout the motion and a force Fis being applied by a rope as shown to prevent the block from sliding too fast. Suppose that while traveling at v=0.1 m/s down the ramp, at d=4meters from the end of the ramp, the rope breaks. Use the work- kinetic energy theorem to calculate the speed, in m/s, of the crate when it touches the bottom of the ramp. Use 9 = 9.8 m/s
Two blocks A (wA=12 N) and B (wB=20 N) are connected by very light string that passes over a frictionless pulley (as shown in Figure 3.8). Block B rest on top of a horizontal tabletop and has a coefficient of kinetic friction against between of 0.15. Block A is suspended on the other end and it does not hit the edge of the tabletop. When the system is released from rest, block A descends to 75 cm. (a) What is the total work done on the system? (b) Using work-energy theorem, what is the speed of each blocks as block A descends to 75 cm?

Here we have a block of mass (m=2.50kg) resting on a place inclined at an angle of ø=30° to the horizontal. The coefficient of static friction between the block and the plane is Ustatic = 0.135 and the block is stationary but just on the point of sliding up the slope. The diagram shows the four forces acting on the block: an applied force F1 acting up the slope, the block's weight mg, the normal reaction force N and the force of static friction, Ff. In this case, the force of static friction acts down the slope, opposing the tendency of the block to move up the slope. Find the the maximum magnitude of the applied force F1 that can be exerted if the block is to remain stationary.
