A 0.12kg rubber ball is dropped from a height of 1.0m above the floor and it bounces back to a height of 0.80m .
How much energy is lost?
How much would a 80.0 kg person weight on Mars, where the acceleration of gravity is 3.93 m/s^2, and on Earths Moon, where the acceleration of gravity is 1.63 m/s^2.
What is an angular acceleration
A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.6m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930m. At that point its engines fai..
A solid cylinder with mass and radius, rotating with angular speed about an axis throughout its center, is set on the horizontal surface for which the kinetic friction coefficient is.
A miniblack hole formed as a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (Assume that your mass is 50).
Dizziness. Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness, What is the radical acceleration (in m/s^2) of the endolymph fluid
Two resistors have resistances R(smaller) and R(larger), where R(smaller)
Assume that we suddenly discovered that all these years we would be wrong about the distance from Earth to the Sun, and it is actually 10 percent greater than we would think. How would that affect our approximation of the distance to the Andromeda..
The skis have a thrust of 200. Sam's speed at the bottom is 43.0. Illustrate what is the coefficient of kinetic friction of his skis on snow?
A person pulls a toboggan for a distance of 40m along the snow with a rope directed 25 degrees above the snow. The tension in the rope is 83N.
A uniform disk of radius 0.46 m is mounted on a frictionless, horizontal axis. A light cord wrapped around the disk supports a 0.58 kg object. When free from rest the object falls with a downward acceleration of 4.1 m/s squared.
A coil is placed in a changing magnetic field and an emf is induced. What happens to induced emf if the rate of change of magnetic field quadruples.
