With what minimum speed must he drive off horizontal ramp

Reference no: EM13319440

A stunt driver wants to make his car jump over 8 cars parked side by side below a horizontal ramp as seen in the figure below. Each car is 1.4 m wide. The vertical height of the ramp is 1.5 m above the cars.

(a) With what minimum speed must he drive off the horizontal ramp to just barely make it across?

(b) If the ramp is tilted upward at 7 above the horizontal, what is the new minimum speed? Provide a sketch.
