Consider a uniform hoop of radius r and mass m rolling without slipping. which is larger, its translational kinetic energy or its rotational kinetic energy?

If an object is moving with a constant acceleration, then it could NOT be OA) changing its direction OB) moving in a straight line OC) moving at a constant speed OD) moving at a constant velocity

While standing on ice, you first throw a tennis ball and then a bowling ball. Which one would cause you to have the greatest negative velocity? Explain using conservation of momentum.

A feverish student weighing 75,000 grams was immersed in 400,000 g of water at 4.0°C to try to reduce the fever. The student's body temperature dropped from 40.0°C to 37.0°C. Assuming the specific heat of the student to be 3.
