Q. A 150 g ball and a 220 g ball are connected by a 36{rm cm}-long, mass less, rigid rod. The balls rotate about their center of mass at 130 rpm. What is the speed of the 150 g ball?
Q. A 29 g bullet is fired straight upward into at rest 1.40kg block and the bullet is embedded in the block. The velocity of the bullet is 510 m/s. Show the conservation of mechanical energy and conservation of momentum are inconsistent before and after the collision and resolve the inconsistency.
An electric wire that has a mass of 5 kg for a 20m length is strung between two poles 20 m apart. What must be the tension in the wire if it is to take .80 seconds for a pulse to travel along the wire from one pole to the other.
A loudspeaker of mass 22 {rm kg} is suspended a distance of h = 2 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has the length of l = 3.90 {rm m}.
A 15 g rifle bullet traveling 190 m/s buries itself in a 3.8 kg pendulum hanging on a 3 m long string, that makes the pendulum swing upward in an arc. Determine the horizontal component of the pendulum's maximum displacement.
Satellite is in a circular orbit about the earth (ME = 5.98 1024 kg). The period of the satellite is 3.70 104 s. What is the speed at which satellite travels.
Find an average magnitude of the induced emf . A bungee jumper, who's mass is 79 kg, jumps from a tall building. After reaching his lowest point, he continues to oscillate up and down, reaching the low point two more times in 8.2 s.

The block is acted upon by its weight w=200lb, a horizontal force Q=600 lb and pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the incline there by sliding the block up it. Establish P and R.
A car of mass 960 travels at a speed of 30 along the straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.88. Take the acceleration due to gravity to be 9.80..
A 10.00kg box on a smooth, frictionless, horizontal surface experiences a downward force of 30n at an angle of 40 degrees to the horizontal. The box moves 1.50 m to the right. What was the work done by gravity.
Five equal negative point charges -q are placed symmetrically around a circle of radius R as shown. Use a rough approximation to express the magnitude of electric field E at a point on the positive x axis a distance R from the center of the circle..
