A motorcyclist leaves a 45 inclined ramp (20 feet high) traveling with an initial speed of v = 150 feet per second. Note: The beginning of the trajectory(departure from ramp) is the point (0, 20). 20' 45 700 feet (a) Determine the parametric representations for x and y as functions of time, where t is in seconds. If entering exact values, use radian measure for angle. x = x(t) = = y = y(t) = (b) Determine the time for the motorcyclist to hit the ground. Ground time= seconds (c) Determine the downrange distance of the motorcyclist. Downrange Distance= feet (d) Will the motorcyclist clear the trucks? YES NO
