Homework Statement
A quarterback claims that he can throw the football a horizontal distance of 184 m. Furthermore, he claims that he can do this by launching the ball at the relatively low angle of 29.7 ° above the horizontal. To evaluate this claim, determine the speed with which this quarterback must throw the ball. Assume that the ball is launched and caught at the same vertical level and that air resistance can be ignored. For comparison a baseball pitcher who can accurately throw a fastball at 45 m/s (100 mph) would be considered exceptional
Homework Equations
.5*184m=92m -adjacent side
90-29.7(theta)=60.3 other angle
Hyp=x/cos theta or 91.42=92/.8686
Opposite ; tan theta=X/92(adjacent side)=54.27 is (.5704*92)
need time so d=(.5)at^2
184=(.5)(-9.80)(t)^2 =-6.13seconds
The Attempt at a Solution
see above - I'm not sure I have the time set up properly. I need a hint as to how to get
started with determining the velocity - just a hint!
