Question
A student releases a ball from rest on an inclined plane and measures that it travels a distance of 0.8 m in a time of 4.0 s. The average speed of the ball isGroup of answer choices1.0 m/s.0.2 m/s.3.2 m/s.2.0 m/s.
Solution
The average speed of an object can be calculated using the formula:
Average speed = Total distance / Total time
In this case, the total distance the ball travels is 0.8 m and the total time it takes is 4.0 s.
So, the average speed = 0.8 m / 4.0 s = 0.2 m/s.
Therefore, the average speed of the ball is 0.2 m/s.
