A pulley of radius 20cm and moment of inertia is suspended from a ceiling and has a long string of negligible mass wound around it. A ball of mass 1kg is connected to the string and released from rest from a height of 2m above the floor. Calculate the acceleration of the ball (assuming that g=9.8m/s2).
In the Bohr model of the hydrogen atom, an electron (mass m=9.1×10?31kg) orbits a proton at a distance of 5.3×10?11m. How many revolutions per second does the electron make
A railroad car of mass 2.00 x 10^4 kg is traveling north 6.00 m/s and collides with a railroad car of mass 1.50 x 10^4 kg traveling south 4.00 m/s, Find the velocity of railroad cars if the lighter car is intially at rest
Professional baseball pitchers can deliver a pitch which can reach the blazing speed of 100 mph (miles per hour). how much kinetic energy does the ball have
If, in actuality, a 750 kg car with an initial speed of 96.0 km/h is observed to coast up a hill to a height of 17.0 m above its starting point, how much thermal energy was generated by friction
A 20-N horizontal force pushes an object along a rough floor so that the object moves with a constant velocity of 7.0 m/s
You roughly estimate that the roommate shines light rays on to the water at an angle of 52.1°. You know that air has an index of refraction of 1.0. Determine the index of refraction of the unknown liquid

A positive charge of 3.2×10-9 C is brought in from infinity to a point (2m,0), How much work did the electric field do
The catapult on an aircraft carrier can take an aircraft from 0 to 192 mph in 12 seconds, at which time the aircraft launches
A train 450 m long is moving on a straight track with a speed of 82.1 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 16.7 km/h. Assuming constant acceleration, determine how long the..
A 4.00-g bullet is moving horizontally with a velocity of +355 m/s, where + sign indicates that it is moving to the right. The bullet is approching two blocks resting on a horzizonta frictionless surface.
The 60kg cradle A is carrying the 12 kg pipe B at the speed of 8 m/s when it hits the rigid wall. suppose all the impacts are plastic, determine the speed of the pipe immediately after the impacts. Neglect friction.
