mgh=1/2 m v^2
solve for v. Notice mass divides out.
A bobsled slides down an ice track starting
(at zero initial speed) from the top of a(n)
165 m high hill.
The acceleration of gravity is 9.8 m/s2 .
Neglect friction and air resistance and determine the bobsled’s speed at the bottom of
the hill.
Answer in units of m/s
