Answer: What we can say is that the ramp's angle could have determined the ball's speed, which increased proportionally. The table shows that the length of the ramp did have an effect on the average distance traveled by the ball. We can see that the further the ball was brown, the further it had traveled when it arrived at the ground. This is because as the ball's speed increased, so did the kinetic energy acting on it, and as the kinetic force increased, so did the friction force.The angle of elevation determines how quickly the ball can travel down the ramp; the more slanted the ramp, the faster the ball can go through it and the greater the average distance travelled by the ball. This is how they are all connected. The greater the average drop time, the greater the average distance traveled, which resulted in a higher horizontal velocity, as horizontal velocity was calculated by dividing the average distance traveled by the average drop time.
