As shown in the figure below, a skateboarder starts at point A on the ramp and rises to point B, a maximum height of h = 2.13 m above the top of the ramp. If the amount of work done against friction is insignificant, determine his initial speed at point A.
The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 5.4 m/s. Neglect nonconservative forces, such as friction and air resistance, and find the height h of the highest point reached by the skateboarder on the right side of the ramp
Consider the skateboarder in the figure below. If she has a mass of 53 kg, an initial velocity of 25 m/s, and a velocity of 13 m/s at the top of the ramp, what is the work done by friction on the skateboarder? Ignore the kinetic energy of the skateboard's wheels.
The figure below shows a motorcycle leaving the end of a ramp with a speed of 39.4 m/s and following the curved path shown. At the peak of the path, a maximum height h above the top of the ramp, the motorcycle's speed is 37.5 m/s. What is the maximum height h? Ignore friction and air resistance. (Enter your answer in m.)
The figure below shows a motorcycle leaving the end of a ramp with a speed of 38.7 m/s and following the curved path shown. At the peak of the path, a maximum height h above the top of the ramp, the motorcycle's speed is 37.2 m/s. What is the maximum height h? Ignore friction and air resistance. (Enter your answer in m.)

A skateboarder with mass m_ s = 52 kg is standing at the top of a ramp which is h_ y = 3.6 m above the ground. The skateboarder then jumps on his skateboard and descends down the ramp. His speed at the bottom of the ramp is v_ f= 6.8 m/s. Randomized Variables m_ s= 52 kg h_ y = 3.6 m V_ y= 6.8 m/s Write an expression for the work, w_ f, done by the friction force...
