Project #66703 - Physics

skatboard shade down 30 degree incline and enters a circular loopof radius 5.0 m,The of the incline   is at the same height as the top of the loop , neglect frictions.

 

a- Determine the min speed,vmin,the skateboarder must have at the top of the incline in order to complete the loop

 

b- find the work done by gravity on the skateboard in going from the top of the incline to the top of the loop

 

c-

suppose the skateboadrder starts from the top of the incline with twice the min speed in part a . Determine the force(both magnitude direction) exerted by the circular track on the skateboard when it is at the topof the loop
