Answer:
The longer car will travel the fastest down the ramp
The car with the least mass will travel the fastest down the ramp
Changing the ramp height will cause the car to travel faster
Explanation:
The longer car will travel the fastest down the ramp
On the table, we are not told what effect a longer car would have on the time taken. We are only told about the mass of car, this means that this would be one of the conclusions you could not draw.
The car with the least mass will travel the fastest down the ramp
We can see on the table that the higher than mass of a car, the quicker the car takes to go down the ramp. This is as the time taken is shorter so it had taken less time. This opposes the statement we are given therefore it should be incorrect.
Changing the ramp height will cause the car to travel faster
On the table, there is not information regarding ramp height meaning that this statement would automatically be incorrect
Hope this helps, have a lovely day! :)
