Aquarterback is throwing the ball to his receiver who is running downfield. he stands 6'5" and launches the ball from a height of 6 ft at and at an angle of 30° from the x-axis. his receiver is 60 yards down the field in the end zone praying for a hail mary play. he catches the ball just 5 inches above the ground determine the angle at which the quarterback needs to throw the ball. how long does it take the ball to get to the receiver? if an opponent is standing 50 yards from the quarterback with arms raised at 5 feet, will he intercept the ball?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
