Objects on the moon's surface have an acceleration due to gravity one-sixth that on the earth's. What would the 40 kg boy weigh on the moon? (Round answer to nearest tenth.)

At what altitude above the earth's surface would the acceleration due to gravity be 4.9 m/s^2? Assume the mean radius of the earth is 6.4x10^6 metres and the acceleration due to gravity 9.8m/s^2 on the surface of the earth.

The muzzle velocity of an armor-piercing round fired from an M1A1 tank is 1770 m/s (nearly 4000 mph or mach 5.2). A tank is at the top of a cliff and fires a shell horizontally.

Work is defined as the use of force to move an object in the direction of that force and is equal to the force times the distance the object moved. How do energy and power relate to work?

2. In regards to the the zonal anatomy of the prostate gland, where do most carcinomas originate?

Two parallel plates are separated by 0.1 mm. A 10 V potential difference is maintained between those plates. If a proton is released from the positive plate, calculate the kinetic energy of the proton when it reaches the negative plate.
