A car slows down at - 5.00 m/s^2 until it comes to a stop after travelling 15.0 m. How much time did it take to stop?

Calculate the magnitude and direction of the electric field 2.0 m from a long wire that is charged uniformly at λ = 4.0 * 10-6 C/m.

Sam, whose mass is 75 kg, straps on his skis and starts down a 50-m-high, 20 frictionless slope. A strong headwind exerts a horizontal force of 200 N on him as he skies. Use work and energy to find Sam's speed at the bottom.

Which causes a rainbow in the sky? a. Sunlight (white light) is refracted as it passes through different layers in the atmosphere. b. Sunlight (white light) refracts when it passes through droplets of water in the atmosphere. c.

A solenoid used to produce magnetic fields for research purposes is 2.4 m long, with an inner radius of 30 cm and 1500 turns of wire. When running, the solenoid produced a field of 1.1 T in the center.
