Chapter 06, Problem 87 Suppose the skateboarder shown in the drawing reaches a height of 1.50 m above the right side of the semicircular ramp. He then makes an incomplete midair turn and ends up sliding down the right side of the ramp on his back. When the skateboarder reaches the bottom of the ramp, his speed is 7.00 m/s. The skateboarder's mass is 66.0 kg, and the radius of the semicircular ramp is 2.10 m. What is the average...

A skateboarder shoots off a ramp with a velocity of 6.8 m/s, directed at an angle of 63° above the horizontal. The end of the ramp is 1.1 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When...

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...
