A record with a 10 cm radius and 200 g mass is dropped vertically onto a freely rotating turntable (meaning the turntable is not being driven by a motor). Frictional forces act to bring the record and turntable to a common angular speed. The radius of the turntable is also 10 cm, and the mass is 2 kg. The initial angular velocity of the turntable is 5 rad/s. (i) What is the final angular velocity of the record and the turntable? (ii) If there is a net frictional torque of 0.1 N·m, how long will it take for the record and turntable to stop rotating?
The acceleration of gravity is 10 m/s2. What is the acceleration of a 39 kg pail of cement that is pulled upward (not sideways) with a force of 421 N? Answer in units of m/s2.

300 J of work are done to compress the gas as, in the same process, 1200 J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the molecules.
A student throws a set of keys vertically upward to his fraternity brother, who is in a window 3.60 m above. The brother's outstretched hand catches the keys 1.20 s later.
The radius of the tires on your car is 0.33m. You drive 1400 m in a straight line. What is the angular displacement of a point on the outer rim of a tire, around the center of tire, during this trip? Suppose the tire rotates in the counter clockwise ..
What is the angular velocity of the disk. If a single bit requires 5 µm of length along the motion direction, how many bits/second can the writing head write when it is 3.0 cm from the axis? display all work and explanations.
A kg steel ball strikes a wall with a speed of m/s at an angle of with the surface. It bounces off with the similar speed and angle. If the ball is in contact with the wall for s, what is the average force exerted on the ball by the wall.
The speed of a passenger train is 16mph faster than the speed of a frieght train. The passenger train travels 330 miles in the same time it takes the frieght train to travel 250miles. find the speed of each train.
A ferry boat transports tourists among three islands. It sails from the first island to the second island, 4.7 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 69.0° west of north..
A charged rod carrying a negative charge is brought near two conducting spheres that are in contact with each other but insulated from the ground. If the two spheres are then separated, what charge does B have, positive, negative or neutral?
The electric field has been measured to be horizontal and to the right everywhere on the closed box. All over the left side of the box E1 = 120 V/m, and all over the right, slanting, side of the box E2 = 250 V/m. On the top the average field is E3..
