Problem 1 - At the instant of leaving the ramp, the skier has a speed of 20 m/s at an angle θA = 30° with the horizontal. In addition to gravity, the wind gust exerts a horizontal acceleration of 2t m/s2 to the left on the skier. Determine the flight time for the skier to strikes the ground. [Hint: You may need to find the root of a higher-order polynomial]
Problem 2 - The motorcyclist increases his speed at the race of v = (0.04s) ft/s2 from A to B along a circular path, where s is in feet and s = 0 at A. If he starts at vA = 3 ft/s, determine the magnitudes of his velocity and acceleration at B.
