Question

Answer parts A and B

Monica is hurrying off to her physics class, jogging down the
sidewalk at a speed of 4.10 m/s . Her friend Manny 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 38.5 m above the street level and directly above
the sidewalk, to throw them to her. Manny throws them
horizontally at a time 4.00 s after Monica has passed below
the window, and she catches them on the run. You can ignore
air resistance.
Part A
With what initial speed must Manny throw the bagels so Monica can catch them just before they hit the ground?
Hint: The bagels move along a projectile trajectory. Find Monica's location when the bagels reach the ground and demand that the bagels have this
same range. When the bagels reach the ground, y final=0m, and they start at y initial at hieght of window. Since v initial has only an X-component,
it is straightforward to calculate the time that they will be in the air. You have to add that time onto the jog time.
