A bowling ball that has a radius of 11.0 cm and a mass of 5.00 kg rolls down a level lane at 2.00 rad/s. Calculate the rotational kinetic energy and the translational kinetic energy of the bowling ball. What is the total kinetic energy of the ball? Assume the bowling ball is a uniform sphere with a rotational inertia of 2mr 2 /5.

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

How much energy must a refrigerator absorb from 225 g of water so that the temperature of the water will drop from 35°c to 5°c
