A bobsled slides down an ice track starting
(at zero initial speed) from the top of a(n)
146 m high hill.
The acceleration of gravity is 9.8 m/s2 .
Neglect friction and air resistance and de
termine the bobsledâ€™s speed at the bottom of
the hill.
Answer in units of m/s.

The change in Kinetic Energy has to be equal to the change in Potentialenergy.
1/2 mv^2=mg*146
v^2=2g(146)
