Tom Brady passes a football – at a velocity of 50 ft/s at an angle of 40 degrees to the horizontal – toward an intended receiver 30 yd straight downfield.The pass is released 5 ft above the ground.Assume that the receiver is stationary,is isolated and that he can catch the ball from the ground (a shoestring catch) up to a height of 7 ft when the ball arrives at his position.Will the pass be completed?If not will it be short or long?If the conditions (launch height,distance to receiver,height for catch) are exactly the same but the quarterback can only launch the football at 45 degrees to the horizontal what is the range of speeds he must give the ball at launch so as to make a completion?
for this question ,use the projectile demo (in Fendt's website) and take 32 ft/s/s for the acceleration of gravity.You can ignore the stated units in the demo as long as you use the appropriate FPS system and use ft/s for speed,ft for displacement (distance),etc.There is no need to convert the units!You must describe in your own words (as if this is a game) what you did to arrive at the answers.Ps:must use the demo.
