Charlie Brown and Lucy are playing catch. Charlie Brown is 15 mdirectly east of Lucy when she says "go long". Lucy throws the balltowards Charlie Brown (directly east) at an angle of 43 degreesabove the horizontal. At exactly the same time, Charlie startsrunning at a constant speed, Vc, directly east. Charlie runs eastfor 3.2 seconds and then catches the ball at the same height fromwhich Lucy threw it.
(a) At what speed did Lucy throw the ball?
(b) At what speed, vc, did Charlie Brownrun?
I think the answers are supposed to be (a) 23 m/s and (b)12.2 m/s but I don't know how to get those answers.
