250 m/s 140 m/s Pivot A uniform stick 1.0 m long with a total mass of 250g pivoted at its center. A 8.0-g bullet is shot through the stick midway between the pivot and one end. The bullet approaches 250 m/s and leaves at 145 m/s. With what angular speed is the stick spinning after the collision?
1. Two particles with masses m1 and m2 respectively are connected by a solid weightless rod of length a, moving freely in a plane. See that the moment of inertia of the system with respect to an axis perpendicular to the plane and passing through center of mass is μa², where u is the reduced mass of the system.
5. Consider a frictionless ice ball with a radius R = 10 m. A box initially at rest begins to slip from the top of the ice ball, and follows the surface until it loses contact. Find the height (with the ground as the reference) of the box at the moment it leaves the surface of the ice ball. [Hint: on the verge of losing contact the normal force on the box from the ice ball becomes zero].

Among the elderly population, a sideway fall is a most frequent cause of hip fracture. An old man of mass 65 kg and height 1.7m was sent to Prince of Wales Hospital due to sideway fall. He slipped and fell laterally down with a straight body. Before falling, his centre of mass was 0.9 m above ground. His centre of mass was on the ground at the end of the fall. The radius of gyration about the anterior-posterior axis at his centre of mass was 0.55 m. (a) Calculate the initial potential energy before his fall. (b) Assuming his potential energy would be converted to linear kinetic energy of his centre of mass and rotational kinetic energy about his centre of mass, calculate the impact velocity v of his centre of mas right before he hit the ground.

1. in the figure, a solid 0.2 kg ball with radius 0.4 m rolls smoothly along a horizontal frictionless plank with linear velocity of 4 m/s before elastically colliding with another solid ball of mass 0.1 kg standing at rest on the top of the ramp at height H = 7 m. After the collision 0.1 kg ball rolls smoothly down the ramp until it reaches the horizontal section at the end of the track, at height h = 2 m, and flies off the ramp. What will be the velocity of the second ball just before it flies off the ramp? %3D
