Question
A ball of mass m is released from A inside a smooth wedge of mass m as shown in the figure What is the speed of the wedge when the ball reaches point B?
Options
A.
B.
C.
D.
Solution
COLM m(v1 cos 45o + v2) + mv2 = 0
⇒ v1 = - 2√2.v2
COME Ki + Ui = Kf + Uf
= 0 +
mv22 + 
⇒ v2 = 
⇒ v1 = - 2√2.v2
COME Ki + Ui = Kf + Uf
= 0 +
mv22 + ⇒ v2 = Create a free account to view solution
