(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 bobsled’s speed at the bottom of

the hill.

Answer in units of m/s.

**bobpursley**, Tuesday, January 11, 2011 at 5:59pmThe change in Kinetic Energy has to be equal to the change in Potentialenergy.

1/2 mv^2=mg*146

v^2=2g(146)
