A) timeinair=375ft/Vi*.866=433/Vi

Vi*1/2=1/2 (33ft/sec^2)433/Vi

vi= sqrt (33*433) ft/sec

sqrt of 14289 ft/sec

Vi= 119.5366

The correct answer is 118 what did I do wrong

and how do I solve for B

If you use g=32.2 instead of 33, you should get the right answer.

b. calculate time in air (as in a) with calculated Vi. Divide this by 2 gives the time when the ball reaches the highest point.

Use

S=Vi.sin30.t + g.t^2/2 (g is -32.2 f/s/s
