Question

You are to throw a ball with a speed vo ata target that is height h above the level at which yourelease the ball. You want the ball's velocity to be horizontal atthe instance it reaches the target. (a) Find the angle above the horizontal at which you have to throwthe ball in terms of h, vo, g, andnumerical constants. (b) Find time t when ball reaches the targetin terms of h and g. (c) Find the horizontaldistance d from the release point to the target in termsof h, vo, g, and numerical constants.(d) Find the speed of the ball just as it reaches the target interms of h, vo, g, and numericalconstants.

Anything will help. thanks!

Explanation / Answer

time    t = 2 h /g Horizontal distance   d = vo sin( 2 h /g) tan = gt / vo            = 2gh / vo speed of the ball just as it reaches the target              v f = (vx2 +vy2 )            vx   = vo cos             vy   =vo sin +gt         vf = [(vo cos )2+ (vo sin+2gh)2]1/2    I hope this helps you!
