A quarterback can run with a speed of vq = 15 mph. He throws a ball with a speed of vb = 35 mph at some unknown angle θ between 30 and 60 degrees, which is measured from horizontal. Neglect air resistance.
- a reciever runs past the quarteback ( just beside him) at speed vq. If the quarterback releases his pass at that instant what would be the angle in degrees that he would have to throw the ball for the reciever to catch it?
In the 1970 National Basketball Association championship, Jerry West made a 60 ft shot from beyond half court to lead the Los Angeles Lakers to an improbable tie at the buzzer with the New York Knicks. Suppose West threw the ball at an angle of 40.0∘ above the horizontal. The basket is 10 ft from the court floor. Neglecting air resistance, estimate the initial speed of the ball. (The Knicks won the game in overtime.)
According to the Guinness Book of World Records the longest home run evermeasured was hit by Roy “Dizzy” Carlyle in a minor league game. The ball travelled188 m (618 ft) before landing on the ground outside the ballpark. (a) Assuming theball’s initial velocity was in the direction of 450 above the horizontal and ignoringresistance, what did the initial speed of the ball need to be to produce such a homerun if the ball was hit in a point 0.9 m above ground level? Assume that the groundwas perfectly flat. (b) How far would the ball be above a fence 3.0 m high the fencewas 116 m from home plate?

If O Bp has magnitude 6.4 m/s, what is the smallest angle it can have (relative to the positive direction of the x axis) for the pass to be legal?arrow_forward
- Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut.
