Q1. A small wooden block with mass 0.900 is suspended from a lower end of a light cord that is 1.50 long. The block is at first at rest. A bullet with mass 0.0106 is fired at the block with a horizontal velocity. The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. As the block has raised a vertical height of 0.725, the tension in the cord is 4.66 .What is the velocity of the bullet originally.

Q2. One simple model for a person running the 100 m dash is to suppose the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.5 m/s in 2.24 s, what will be his total time?

Q3. An insulating spherical shell with inner radius 25.0 rm cm and outer radius 60.0 rm cm carries a charge of + 150.0 mu {rm C} uniformly distributed over its outer surface. Point a is at the center of the shell, point b is on an inner surface and point c is on the outer surface.
