My friend and I are doing a science project in which we are trying to calculate the initial velocity and projectile motion of a basketball being thrown from an initial height of 67 inches to a final height of 10 feet (120 inches) taking about 1.0 seconds to reach its destination. How do we calculate the initial velocity of the shot?

Just reverse the problem.    Can you drop the ball from a height of 10 feet and calculate its velocity when it reaches a height of 67 inches?   You can use the formula   v^2  =  2 g s,  where g  =  32 f/s^2,  s  =  10 ft  -  67 inches.
