Suppose the dim-looking headlight on the right is actually a small light on the front of a bicycle. What can you conclude about the distance of the motorcycle and bicycle?

Quantum theory, where may the electrons of an atom be found

A car traveling 25 m/s to the north collides with a car traveling 15 m/s to the south. Each car has a mass of 1100 kg. If the system is defined as the two cars, what is the change in momentum of the system due to the collision?

Calculate the maximum acceleration of a car that is heading up a 4º slope (one that makes an angle of 4º with the horizontal) under the following road conditions.

The two main parts of a wave are the a. swell and whitecap. c. crest and trough. b. wavelength and wave height. d. rise and dip.

A block of mass m=16.8 kg is sliding on a surface with initial velocity v=23.2 m/s. The block has a coefficient of kinetic friction μk = 0.426 with respect to the surface and is being pushed by a force of magnitude F=86.

Two children are pulling and pushing a 30.0 kg sled. The child pulling the sled is exerting a force of 12.0 N at a 45o angle. The child pushing the sled is exerting a horizontal a force of 8.00 N. There is a force of friction of 5.00 N.
