The coefficients of kinetic friction on the incline and the plane are negligible. The 3.0 g-box is released (from 10.0 cm height) and would elastically hit the 3.0 g-pendulum bob. What would be the velocity of the box right after the collision? How high would the pendulum bob go if the pendulum length is 4.1 cm?
