Question 22126: A ball that is hit or thrown horizontally with a velocity of v feet per second willtravel a distance of d feet before hitting the ground, where d=v*(h/4.9) and h is the height in feet from which the ball is hit or thrown. Use the properties of radicals to rewrite the formula.
How far will a ball that is hit horizontally with a velocity of 45 feet per second at a height of 0.8 feet above the ground travel before hitting the ground.
An automotive engineer is trying to design a safer car. The maximum force a road can exert on the tires of the car being redesigned is 2000 pounds. What is the maximum velocityv in feet per second at which this car can safely round a turn of radius 320 feet? Use the formula v+(F*r/100), where F is the force the road exerts on the car r is the radius of the turn.

You can put this solution on YOUR website!
d=v*(h/4.9)
d=45(0.8/4.9)=7.35 ft.
v=F(r/100)
v=2000(320/100)
v=6400 ft. per second
Does't sound right to me
Check your formula again.
