Question

Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 3.05 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 51.0 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 5.50 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance.


* With what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground?


* Where is Henrietta when she catches the bagels?

Explanation / Answer

x(t) = x(0) + v(0)t + 1/2at^2 36.2 = 0 + 0 + 1/2(-9.8)t^2 using that formula i got the time it took for the bagel to drop, which is t=2.77s
