A popular daredevil trick is to complete a vertical loop on a motorcycle. This trick is dangerous, however, because if the motorcycle does not travel with enough speed, the rider falls off the track before reaching the top of the loop. What is the minimum speed necessary for a rider to successfully go around a vertical loop of 10 meters?

1. mg=m*v^2/r

Vmin=sqrt(g*r)= sqrt(9.8*10)

=9.9m/s
