A Drag Racer accelerates at a uniform rate from it's starting point.
It travels the last 1/4 of the distance from the starting point
to the finish line in 3 seconds.
How long did it take to travel the entire
distance from starting point to finish line?
This uses the Quadradic Formula:
A*X*X + B*X + C = 0
=> X = (-B + Sq-Rt(B*B - 4*A*C))/(2*A)
=> X = (-B - Sq-Rt(B*B - 4*A*C))/(2*A)
A helium baloon carrying a baseball goes up
to a height h feet where it pops and
releases the ball. The ball travels the
last 3000 feet in 5 seconds.
Assume no friction and acceleration
due to gravity to be 32 ft/sec/sec.
How high was the ball when it dropped?
