Hello, beetz!
Given: horizontal distance = 68 m
angle with respect to horizontal: 35.8°
time object spends in the air: 3.0 seconds.
Find the initial velocity.
We're expected to know this formula: .
. . where: .
We are given: .
. . Hence, we have: .
The object is on the ground when and
So we have: .
Therefore: .
