Jim rides his skateboard down a ramp that is in the shape of a quarter circle with a radius of 5.00 m. At the bottom of the ramp , Jim is moving at 9.00 m/s. Jim and his skateboard have a mass of 58.4 kg. How much work is done by friction as the skateboard goes down the ramp?
1 answer:
Answer:
Wfr=-496.4 J
Explanation:
The total work of the motion is describe
x=5.0m
v=9.0 m/s
m=58.4kg
The Work of the friction can be find without know the coefficient however knowing the total work and the work done by the gravity down a ramp can find the work of the friction
