A car approaches the top of a hill that is shaped like a vertical circle with a radius of 58.5 m. What is the fastest speed that the car can go over the hill without losing contact with the ground?
Solution
N - mg = mv^2 / r ;
if it loses contact , N= 0 ;
0 - mg = mv^2/ r ;
v^2 = gr ;
v = ( gr )
v = ( 9.8 * 58.5 )
v = 23.94 m /s <-------ans
