The problem is this: There are two blocks of unknown masses M1 and M2. M1 is sitting on a frictionless table and M2 is attached to m1 by a massless string and is hanging over the edge over a pulley. If m1 is four times more massive than m2, how far will m1 travel in 0.633 seconds? So far I've...

well, I know that the height the ball has to travel in order to clear the top of the net is .91 m. I'm not sure if this even matters in this problem. the Vxo=cos55 v Vyo=sin55 v the total distance the ball has to travel is 18m. Where my problem lies is with the initial height difference of...

A ski jumper acquires a speed of 111.4 km/hr by racing down a steep hill. He then lifts off into the air from a horizontal ramp. Beyond this ramp, the ground slopes downward at an angle of q = 45°. Assuming the skier is in free-fall motion after he leaves the ramp,at what distance down the slope...

A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.52 m directly above the back line, and the ball's initial velocity makes an angle q = 55° with respect to the ground. At what initial speed...
