A small wooden block with mass 0.750 kg is suspended from the lower end of a light cord that is 1.54 m long. The block is initially at rest. A bullet with mass 0.0128 kg is fired at the block with a horizontal velocity v0. The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. When the block has risen a vertical height of 0.700 m, the tension in the cord is 4.98 N. What was the initial speed v0 of the bullet?
The figure shows a small wad of putty colliding into a bar. The bar is initially hanging at rest from a pivot located at one end of the bar. The collision is completely inelastic. The bar has mass M = 3.78 kilograms and length L = 1.12 meters. The putty wad has mass m = 131 grams and is moving horizontally with vi = 1.67 m/s just before colliding with and sticking to the bar. The putty wad collides with the bar at d = 0.83 meters from the pivot. Note that the size of the putty wad is negligible compared to the length of the bar. Calculate the angular velocity (rad/s) of the bar just after the collision.
One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 29 m/s. The masses of the two objects are 2.8 and 8.8 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially.

Assume that the coefficient of kinetic friction between the block and the surface μk is 0.43.

What is the initial velocity vi of the metal object before it hits the block in m/s? Keep three significant figures for the answer.
