🤓 Based on our data, we think this question is relevant for Professor Woods' class at USF.

Solution: A stunt driver wants to make his car jump over 8 cars parked side by side below a horizontal ramp (Fig. 3-46).(a) With what minimum speed must he drive off the horizontal ramp? The vertical height of the ramp is 1.5 m above the cars and the horizontal distance he must clear is 22 m.(b) If the ramp is now tilted upward, so that “takeoff angle” is 7.0° above the horizontal, what is the new minimum speed?

Problem

A stunt driver wants to make his car jump over 8 cars parked side by side below a horizontal ramp (Fig. 3-46).
(a) With what minimum speed must he drive off the horizontal ramp? The vertical height of the ramp is 1.5 m above the cars and the horizontal distance he must clear is 22 m.
(b) If the ramp is now tilted upward, so that “takeoff angle” is 7.0° above the horizontal, what is the new minimum speed?
