Steve Young stands on the 20-yard line, poised to throw long. Hethrows the ball at initial velocity v0 equal to 15.4 m/s andreleases it at an angle θ equal to 45.0∘ .
1) Having faked an end around, Jerry Rice comes racing pastSteve at a constant velocity VJ equal to 8.00 m/s, heading straightdown the field. Assuming that Jerry catches the ball at the sameheight above the ground that Steve throws it, how long must Stevewait to throw, after Jerry goes past, so that the ball fallsdirectly into Jerry's hands? (Express your answer to threesignificant figures.)
2) Jerry is coming straight past Steve at VJ equal to 8.00 m/s.But just as Jerry goes past, Steve starts to run in the samedirection as Jerry with VS equal to 1.40 m/s. How long must Stevewait to release the ball so that it falls directly into Jerry'shands? (Express your answer to three significant figures.)
