Homework Statement
In a movie stunt, a 65 kg skier starts from a rest position at the top of a hill 30m high. She slides down the hill to the bottom, where she collides with a 45 kg stationary skier. The collision is completely inelastic. Find the final velocity of the skiers.
Homework Equations
M1V1 +M2V2= (M1+M2)V
ET'=ET'
ET'=(M1+m2)gh ( ithink this is relevant?)
The Attempt at a Solution
ET'= (65+45)(9.8)(30)
ET'= 32,340
32,340= 1/2mv2
Sq RT[(32,340)(2)/(65)] = velocity of skier going down hill?
=31.5 m/s (100 km/h + seems kinda fast for a skier)
