Q. A car is slides down an icy driveway that slopes at an angle of 20 degrees. What is the acceleration of the car? Assume that the friction between the tires and the icy pavement is negligible

Q. A wave in the ocean has amplitude of 3 m. Winds pick up suddenly, increasing the wave's amplitude to 6 m. How does this change in amplitude affect the wave's frequency and the amount of energy it transports?
