Need help solving the number of force in plane, centripetal force and if all forces are balanced.
Transcribed Image Text:A 75kg skateboarder (including the skateboard) wants to figure out how fast he
needs to go over a hill in order to catch air! Answer all questions for the case under
which he just barely loses contact with the ground as he reaches the top of the hill
as shown. Neglect drag and the size of the skateboarder.
number of forces in plane:
centripetal force:
Are all forces balanced?
What is the centripetal net force on the skateboarder?
unit
What is the skateboarder's centripetal acceleration?
unit
11m
What is the skateboarder's speed?
unit
Would the skateboarder catch air if he reached the peak of the hill with a speed of
14m/s?
Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
