A 2.00m long pendulum, with a mass of 250 gr, collides with a 95.0 gr sticky ball seating in the pendulums path, at the edge of a horizontal surface. the collision takes place when the pendulum is passing through its lowest point, and during the collision, the ball sticks to the pendulums bob.
a. What is the velocity of the system just after the collision
b. How high will the system rise from the horizontal surface after the colision?
