A skier starts at the top of a frictionless slope and pushes off with a speed of 3.0 m/s. The elevation of the slope is 40 m. She skis down the slope to a valley with elevation 0.0 m and then glides to the peak of an adjacent slope that is at an elevation of 25 m. Calculate her speed at the second peak

A 55.0 KG skier with the initial speed of 10.0 M/S Coast of a 2.50 M hi rise as shown in figure 6.23. Find his final speed at the top given that the coefficient of friction between her skis and the snow is 0.0800. Can't find the distance traveled up the incline assuming a straight line path as shown in the figure. m/s ? posting a photo of the figure for reference.

The speed of a crate traveling on a horizontal frictional surface changes from vi=13 m/s to vf=11.5 m/s in a distance of d=8.5 m. (A) how long in seconds did it take for the crate to slow by this amount, assuming the acceleration is constant? (B) if the crate has a mass of 1kg, what is the power supplied to the crate by friction? (C) what is the coefficient of kinetic friction between the crate and the surface uk?

Neglecting friction and air resistance, a car with an initial velocity of 43.1 km/h coasts up a hill and comes to stop at the hill's top. What must be the height of the hill (in meters)? Hint: you do not need the car's mass to solve this problem, but if interested to solve the problem using kinetic and potential energies you can use a mass of 2000kg for the car.

When the 5-kg box reaches point A it has a speed VA = 12 m/s. (Figure 1) Figure ( 1 of 1 y=x 9 m B 9 m

A sled is initially given a shove up a frictionless 23 degree incline. It reaches a maximum verticle height 1.22 m higher than where it started at the bottom. What was the initial speed?

A 56.32-kg skier with an initial speed of vi=44.29 m/s coasts up a H=15.4-m-high rise as shown in the figure.  The slope angle is theta=20.41. What is her final speed at the top? Assume the coefficient of friction between her skis and the snow is 0.17 (Hint: Find the distance traveled up the incline assuming a straight-line path as shown in the figure.) Use g = 10 m/s2.
