Homework Statement
Determine the initial velocity of a ball which starts 3ft above the ground travels a distance of 180ft and has an angle of 30 degrees; taking into account gravity as 32.2ft/s2.
Homework Equations
I have been having trouble as to how to get the time in which it takes the ball to hit the ground. NOTE this is the second part to an impulse question. Which states that a ball traveling 80ft/s is struck by a bat. Impact time of .015s and leaves the bat at a 30 degree angle. I need to know its leaving velocity to find out the Impulse Force...
The Attempt at a Solution
Voy = -32.2t/sin30
Voy2 +64.4*3 = 0
Voy = 13.9ft/s
13.9ft/s = -32.2t/sin30
t = .22s
Vox = 818ft/s
Vo = 818ft/s...
Which does not sound right to me =\
