A 2000 kg car rounds a curve of radius 66 m banked at an angle of 13°. What is the magnitude of the friction force required for the car to travel at 80 km/h?.

Lexy is correct because angle r is between the incident wave,  n  = 0, and a diffracted wave.

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m
