A pendulum of length L = 1.0 meter and bob with mass m = 1.0 kg is released from rest at an angle 30° from the vertical. When the pendulum reaches the vertical position, the bob strikes a mass M = 3.0 kg that is resting on a frictionless table of height h = 0.85 m. You may assume the string is massless, and drag is negligible. a. Calculate the speed of the bob just before it strikes the box (i.e., when the pendulum string hangs straight down). b. Calculate the speeds of the bob and the box just after they collide elastically. c. Determine the impulse that acts on the box during the collision. d. Determine how far from the bottom edge of the table, Ax, the box lands.

A pendulum of length L = 1.0 meter and bob of mass m = 1.0 kg is released from rest at an angle θ = 30 degrees.
