a) What minimum launch speed (at point c) is required to make across the canyon? Neglect air resistance.
b) With the minimum launch speed at point c, what is the magnitude of the car’s velocity at point b? (Assume that only conservative force acts on the car as it approaches the lower end of the ramp at point b up to the edge of the ramp at point c)
c) What should be the minimum average power of the rocket (expressed in horsepower) to be able to do the stunt?
Transcribed Image Text:Clark tries to do a daredevil stunt by jumping a canyon in a rocket-
powered car. The 700-kg car starts from rest at point a accelerates
uniformly as is reached the lower end of the ramp Ax = 260 m away. The
canyon is x = 350 m wide, with the opposite rim at the same height. The
launch ramp has a height of y = 12 m above the rim and the angle of the
%3D
end of the ramp is 0= 45 deg.
