Q. An electric motor turns a flywheel through a drive belt that joins a pulley on the motor and a pulley that is rigidly attached to the flywheel. The flywheel is a solid disk with a mass of 88.0 kg and a radius R = 0.625 m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of 0.230 m. The tension Tu in the upper (taut) segment of the belt is 152 N, and the flywheel has a clockwise angular acceleration of 1.67 rad/s2. Find the tension in the lower (slack) segment of the belt.
Q. A gas expands when 502 J of energy is added to it as heat. The expanding gas does 422 J of work on its surroundings.
What is the overall change in the internal energy of the gas?
A child loses his balloon, which rises slowly into the sky. If the balloon is 23 cm in diameter as the child loses it, what is its diameter at the following altitudes? Assume that the balloon is very flexible and so surface tension could be neglec..
Two large metal plates of area 1.20m2 face each other. They are 4.8cm apart and have equal but opposite charges on their inner surfaces. The strength of the electric field between them is 63N/C.what is the magnitude of the charge on each plate.
A space vehicle is coasting at a constant velocity of 28.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.523 m/s2 in the +x direction.
A 23 bullet traveling 240 penetrates a 4 block of wood and emerges going 170. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.

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..
If the coefficient of kinetic friction between the box and the roof is 0.55, with what speed must you push the box to have it gently come to rest right at the edge of the roof.
A cosmic-ray proton in interstellar space has an energy of 17.0 MeV and executes a circular orbit having a radius equal to that of Jupiter's orbit around the Sun (7.78 x 10^11 m). What is the magnetic field in that region of space.
A gymnast with mass m1 = 40 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 110 kg and length L = 5 m. Each support is 1/3 of the way from each end. at first the gymnast stands at the left end of..
A 1.20 liter flask contains a certain quantity of ideal gas at 305 K. next an equal number of molecules of the same gas are added to the flask, after which the absolute pressure is 1.30 times its original value. What is the final temperature.
