Homework Statement



A stunt driver wants to make his car jump over 10 cars parked side by side below a horizontal ramp. if the horizontal distance is 80 ft and vertical distance is 6 ft., what is the minimum speed must the driver drive off the ramp?

Homework Equations



vx=v°*cos(θ)
v°y=v°sinθ


The Attempt at a Solution


80/cos45=113
6/sin45=8.5

Are you going to attempt this problem?
 


i did
 
You should look up Kinematic Equations in your book or with google.
