A small sphere of charge q1 = 0.872 µC hangs from the end of a spring. When another small sphere of charge q2 = -0.642 µC is held beneath the first sphere, the spring stretches by d = 3.57 cm from its original length and reaches a new equilibrium position with a separation between the charges of r = 4.80 cm. What is the force constant of the spring?
A gun shoots bullets that leave the muzzle with a speed of 341. If a bullet is to hit a target 177 away at the level of the muzzle, the gun should be aimed at a point above the target.
A daredevil is shot out of a cannon at 43 degrees to the horizontal with an initial seed of 25m/s. A net is positioned at a horizontal distance of of 50m from the cannon from which it is shot. At what height above cannon should the net be placed i..
What is the electric potential energy of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)" Use = 8.85 10 12 for the permittivity of free space.

A person wearing a safety belt can withstand an acceleration of -3.0 x 10^2 m/s2. How thick must barriers be to safely stop a car that hits a barrier at 112 km/h.
a 500 g ball swings in a vertical circle at the end of a 1.5-m-long string. When the ball is at the bottom of the circle the tension in the string is 15 N. What is the speed of the ball at that point?
If the orientation of the spacecraft is to be changed by 30.0°, for what time interval must the gyroscope be operated.
What is speed of the wind what is coefficient of static friction
A uniform rod of length 0.790 m and mass 14.50 kg is balanced on a sharp edge at 0.650 m from the left end. At the left end hangs a mass of 45-kg and the right end hangs an unknown mass so that the whole assembly is in equilibrium.
How many drops of water are in all the oceans on earth? Assume that contains 25 drops of water. Remember that this is an order-of-magnitude problem, so you should expect that you will only find rough estimates for the numbers you require.
The loaded cab of an elevator has a mass of 3.0 x10^3 kg and moves 171 m up the shaft in 23s at constant speed. At what average rate does the force from the cable do work on the cab.
