The picture shows a ball rolling up a ramp
Which statement best describes the motion of the ball?
A. The balls speed is increasing
B. The balls speed is decreasing
C. The balls motion is constant
D. The balls motion is stopping
A. The ball's speed is increasing
If it is rolling up I suspect it is slowing down.
You are correct. If the ball is rolling up a ramp, it is moving against gravity, which means it is working against a resistive force. This resistive force would cause the ball to slow down, so the ball's speed is decreasing.
To determine the motion of the ball in the picture, we can analyze the forces acting on the ball. When a ball is rolling up a ramp, the force of gravity is acting vertically downwards and the force of the ramp is acting upwards along the ramp.
Since the ball is rolling up the ramp, it means that the force of the ramp is greater than the force of gravity. This implies that there is a net force acting in the direction of motion, causing the ball to accelerate. Therefore, the ball's speed is increasing.
Therefore, the correct statement would be:
A. The ball's speed is increasing.
