A ball rolls over the edge of a table with a horizontal velocity v m/s. The height of the table is 1.6 m and the horizontal range of the ball from the base of the table is 20 m. What is the magnitude and direction of the ball's acceleration right before it touches the ground?
Thank you for the opportunity to help you with your question!
Acceleration due to gravity is always 9.8 meters per seconds squared, straight down. As there are no other factors accelerating the ball, that's the final answer. Neither the ball's mass, nor velocity if it is already moving, effect its acceleration.
Please let me know if you need any clarification. I'm always happy to answer your questions.
