A ball is thrown vertically upward direction with an initial velocity 50 km/s. What's the maximum height?
That's quite high. Can you explain to me why the ball will stop at the maximum height?
Of course. When a ball is thrown vertically upward, it moves against the force of gravity. Eventually, gravity will slow down the ball's speed until it eventually comes to a stop at its maximum height before falling back down to the ground.
