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...

A 75 kg snowboarder slides down a hill that has a vertical drop of 6.0 m and is inclined at 31owith respect to the horizontal. The initial speed of the snowboarder at the top of the hill is 5.0 m/s. The coefficient of kinetic friction between the ramp and the snowboard is 0.20. A) Calculate the acceleration of the snowboarder The acceleration is 3.40 m/s B) Calculate the total work done on the snowboarder C) Using the work-energy theorem, calculate...

4. A 20.0 kg box at the top edge of a ramp has a speed of 3.40 m/s as it begins to slide down the ramp. The ramp has a slope of 28.0° above horizontal. It moves down the ramp a distance of 5.30 m before coming to a stop. After drawing the picture and the FBD of the forces on the box, answer the following questions using only Energy and Work. (a) What is the network done on the...

As shown below (not to scale), a block of mass starts from rest
and slides down a frictionless ramp of height h. Upon reaching the
bottom of the ramp, it continues to slide across a flat
frictionless surface. It then crosses a "rough patch" on the
surface of length d=10m. This rough patch has a coefficient of
kinetic friction uK=.1. After crossing the rough patch, the block's
final speed is vf=2m/s. What is the height of the ramp? Hint: I...
