Question 357390
You could start with the general formula for the height of an object (s) as a function of time (t), s(t), propelled upwards with an initial velocity ({{{v[0]}}}) from an initial height ({{{h[0]}}}):
{{{s(t) = (1/2)gt^2+v[0]t+h[0]}}} where g (constant of acceleration due to gravity) = -32 ft/sec^2.  So substitute g = 32, {{{v[0] = 76}}}, and {{{h[0] = 2}}}
{{{highlight(s(t) = -16t^2+76t+2)}}}
Note: The acceleration due to gravity is negative because it is in a downward direction.
