i have a physics worksheet but i do not understand the question.
"A ball is kicked such that it moves horizontally at 3 m/s and falls off a 45 m tall cliff."
1.What is the ball's horizontal and vertical acceleration?
i know the vertical acceleration is 9.8 m/s^2 but what about the vertical?

If the air resistance is neglected horizontal acceleration is zero. Vertical acceleration is always 9.8 m/s²

1. Do we have forces in vertical direction? You are correct we do it is the force of gravity and acceleration is g=9.8m/s^2
2. Do we have any forces acting on the ball in the horizontal plane? If you think that we have none (ignoring air resistance) you are correct again! So a=0 m/s^2
