A sled and rider, gliding over horizontal, frictionless ice at 4.5 m/s, have a combined mass of 74 kg. The sled then slides over a rough spot in the ice, slowing down to 2.6 m/s.

The function x = (7.8 m) cos[ (5πrad/s) t + π/3 rad] gives the simple harmonic motion of a body. At t = 4.

Consider two spaceships, each traveling at 0.50c in a straight line. Ship A is moving directly away from the Sun and ship B is approaching the Sun. The science officers on each ship measure the velocity of light coming from the Sun.

The 20 or so minerals that make up most of the rocks of earth's crust are known as?

How does the angle at which a ray of light strikes a pane of window glass compare with the angle at which the light passes out the other side?

A 20 kg mass was lifted 3.0 m from the ground. What is the work being done on the mass?

Which type of energy is commonly referred to as kinetic energy? A) gravitational B) mass C) motion D) wind

A 60-gallon water heater is initially filled with water at 66°F. Determine how much energy, in Btu, needs to be transferred to the water to raise its temperature to 104°F. Given: The water properties at an average water temperature of 85ºF rho = 62.
