Answer:
V = 38.582 m/s
Explanation:
Initial Vertical Velocity = 0
Let's use the motion equation given below to solve for the final vertical velocity:
Here a = 9.81 m/s^2
and s = 30 m
Solving for v, we get:
v = 24.261 m/s
This is just the vertical velocity, to get the total velocity we need to add the horizontal component of velocity with this:
Total velocity = Sqrt ( Horizontal Velocity^2 + Vertical Velocity^2)
where and
V = 38.582 m/s
