7.
Since air resistance is negligible the horizontal velocity of the car is constant.
Evidence
Reasoning
The car was launched from four heights.
Evidence
Reasoning
Horizontal and vertical displacement were measured with a meterstick.
Evidence
Reasoning
When launched from 0.5 cm the time in the the air was 0.3 s.
Evidence
Reasoning
Because the initial vertical velocity is zero, the equation y= 1/2at
2
can be used to calculate the time.
Evidence
Reasoning
The ball was launched three times from this height and the horizontal displacement was 0.3 m, 0.28 m, and 0.29 m.
Evidence
Reasoning
The calculated time was plotted against the average horizontal displacement and a best fit linear curve was applied.
