Given information
A stunt driver wants to make his car jump over cars parked side by side below a horizontal ramp.
The vertical height of the ramp is above the cars and the horizontal distance he must clear is .
Step-by-step explanation
Step 1.
When the car moves over cars, at the end the car is vertical above at a distance of .
we have the formula , for horizontal distance .Here is distance, is velocity and is time.
From this formula we get the time of flight.
Substituting the values Or
Now for vertical motion we use the equation of motion Here h is height which is equal to . is initial velocity in vertical direction, which will be zero as in vertical direction the velocity is zero. is acceleration due to gravity and is time of flight.
