49. (a) 43.2 m (b) (9.66î – 25.6 j) m/s (c) Air resistancewould ordinarily make the jump distance smaller and thefinal horizontal and vertical velocity components bothsomewhat smaller. If a skilled jumper shapes her bodyinto an airfoil, however, she can deflect downward the airthrough which she passes so that it deflects her upward,giving her more time in the air and a longer jump.2L/c- CHALLENGE PROBLEMS49.

Emmy kicks a soccer ball up at an angle of 45° over a level field. She watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. Assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. Consider only the time that the ball in the air, after being kicked but before landing. Take "north" and "up" as the positive x- and y-directions, respectively, and use g x 10 m/s2 for the downward acceleration due to gravity.

In an article on the use of the sling as a weapon, the author states that a skilled slinger can sling a rock a distance of about 384 m. What is the minimum speed the rock must have when it leaves the sling to travel exactly 384 m?
