1.The quarterback Q throws the football when the receiver R is 30 yards away. The receiver's velocity is constant at 10 yd/sec, and he catches passes when the ball is 6 ft. above the ground. If the quarterback desires the receiver to catch the ball 2.5 sec. after the launch instant shown, determine the initial speed v0 and angle, theta required
2.A fireworks shell is launched vertically from point A with speed sufficient to reach a maximum altitude of 500ft. A steady horizontal wind causes a constant horizontal acceleration of 0.5ft/sec^2, but does not affect the vertical motion. Determine the deviation at the top of the trajectory caused by the wind.
