Emily throws a soccer ball out of her dorm window to allison, who is waiting below to catch it. if emily throws the ball at an angle of 30º below the horizontal with a speed of 14m/s, how far from the base of the dorm should allison stand to catch the ball? assume the vertical distance between where emily releases the ball and allison catches it is 8.0m.

d = 9.1 m

Explanation:

As we know that initial speed of the ball is given as

it is projected at an angle of 30 degree below the horizontal

so we have

now we know that in y direction the displacement of the ball is 8.0 m

also the acceleration in y direction is due to gravity

so we will have

Now in the same time the horizontal distance moved by the ball is given as

i would say
