Two children are sliding down a snowy hill which is inclined by 45.6 degrees with respect to horizontal. One has a rough sled which has a coefficient of kinetic friction between it and the snow of uk = 0.364; the other has a slippery sled which has a coefficient of kinetic friction between it and the snow of uk = 0.138. If both children start at the top of the 46.3 m tall hill initially at rest, what is the difference in speed between these two sleds at the bottom of the hill?

Two blocks are positioned on surfaces, each inclined at the same angle 45.6 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines, so the blocks can slide together. The mass of the black block is 4.10kg and the coefficient of kinetic friction for both blocks and inclines is μk 0.370. Assume static friction has been overcome and that everything can slide. A) What must...

Driving down a hill inclined at an angle θ with respect to horizontal, you slam on the brakes to keep from hitting a deer. Your antilock brakes kick in, and you don’t skid. (a) Analyze the forces. (Ignore rolling resistance and air friction.) (b) Find the car’s maximum possible deceleration, a (expressed as a positive number), in terms of g, θ, and the relevant coefficient of friction. √ (c) Explain physically why the car’s mass has no effect on your...

A 1450 kg car begins sliding down a 12.0 ° inclined road with a speed of 34.0 km/h.The engine is turned off, and the only forces acting on the car are a net frictional force from the road and the gravitational force. After the car has traveled 45.0 m along the road, its speed is 50.0 km/h. (a) How much is the mechanical energy of the car reduced because of the net frictional force? (b) What is the magnitude of...

A box of physics books slides down a ramp inclined at an angle of 40 degrees to the horizontal. The total length of the ramp is 10m. The coefficient of kinetic friction between the box and the ramp is .2 for the top 8m and zero for the bottom 2m. Upon reaching the bottom of the ramp, a spring bounces the box back upward. (a) Find the distance that the box travels back up the ramp on the return bounce....

A 50 kg crate slides down a ramp that is inclined by 30 degrees from the horizontal. The acceleration of the crate parallel to the surface of the ramp is 2.0m/s^2, and the length of the ramp is 10m. Determine the kinetic energy accumulated by the crate when it reaches the bottom of the ramp if it started from rest at the top of the incline. Calculate the amount of energy lost by the crate due to friction in its...
