Question

A golf ball rolls off a horizontal shelf with a velocity of 0.25 m/s. If it takes the ball 1.7 seconds to hit the ground, how high was the table? Choose the closest answer.

Answer 1

Step-by-step explanation:

Given:

V₀ = 0.25 m/s

t = 1.7 s

g = 9.8 m/s²

_____________

H - ?

H = V₀*t + g*t²/2

H = 0.25*1.7 + 9.8·1,7² / 2 = 14.6 m
