Question

Once the ball leaves the ramp, and just before it hits the table, which of the following is true for the motion of the ball? Select all that apply. Once the ball leaves the ramp, and just before it hits the table, which of the following is true for the motion of the ball? Select all that apply. -there is no force acting on the ball -the ball follows a parabolic trajectory -there is a constant force in the horizontal direction -the only force acting on the ball is the gravitational force in the downward direction -the horizontal component of the ball's velocity is decreasing

Explanation / Answer

When the ball leaves the ramp, it possesses horizontal velocity. Hence, it is the case of a horizontal projectile.The only force acting on it is gravitational force which is acting in vertically downward direction. Options: -there is no force acting on the ball Ans: False. The ball experience gravitational force. -the ball follows a parabolic trajectory Ans: True. The ball falls in a parabolic trajectory similar to a projectile. -there is a constant force in the horizontal direction Ans: False. The ball doesn't experience any force in horizontal direction. -the only force acting on the ball is the gravitational force in the downward direction Ans: True. It is the only force acting in vertically downward direction. -the horizontal component of the ball's velocity is decreasing Ans: False. As there is no force acting in horizontal direction, there is no acceleration in that direction, and horizontal component of velocity remains constant.
