Would anyone know the correct answer to this Grade 8 Science question?
Use the diagram and table below to answer the question.
Toy Gun Experiment
Ball Mass (g) Time (s)
1 55 2.1
2 45 1.6
3 63 2.3
4 35 1.2
A student has a toy gun that shoots balls with the same amount of force every time. The student loaded the gun with five balls that had different masses but that were the same size and shape. He shot the gun four times and measured how long it took each ball to travel 3 meters, and his results are shown in the table above. The fifth ball in the gun has a mass of 75 grams. Based on the trend in the table, which of the following should the student predict will happen when he shoots the fifth ball?
It will take the ball less than 2.3 seconds to travel 3 meters.
It will take the ball more than 2.3 seconds to travel 3 meters.
It will take the ball less than 1.2 seconds to travel 3 meters.
It will take the ball exactly 1.2 seconds to travel 3 meters.
