Question

A ball thrown horizontally with speed vi = 30.0 m/s travels a horizontal distance of d = 50.0 m before hitting the ground. From what height h was the ball thrown? You should compile a list of values, including known and unknown quantities. Identify the following terms as knowns or unknowns.

Answer 1

Step-by-step explanation:

50 m / 30 m/s = 1.667 s flight time

to fall for 1.667 s sec

d= 1/2 at^2

= 1/2 ( 9.81)(1.667 )^2= 13.63 m = height
