Trajectory Calculator by David Fahim

Quadratic Equation (Standard Form): 0 = ax2 + bx + c

In the case of calculating the trajectory of an object: h = at2 + bt + c
a is the value of gravity (negative feet per second)
t is the seconds in air (automatically used with a to get the intial velocity b upon calculation)
c is the number of initial feet (height at which the object was launched (defaults to 0))

Enter the values for the quadratic equation below:
