Which graph shows a constant acceleration (>0)?

A) Acceleration vs time graph pointing up diagonally

B) Velocity vs time graph pointing up diagonally

C) Horizontal V vs T graph

D) Distance vs time graph pointing up diagonally

In Part 1, given an elevationh and a distance between the air track legsd, you obtained an acceleration ofa = 2.75 m/s².

What would you get for your value of acceleration (in m/s²) if the distance dwas reduced by 28% while keepingh constant?

Round your calculation to 2 decimal places.

part 3 given an elevation h and a distance between the legs d, what happens if you increase the mass M of the glider? This question is talking about acceleration. Does it decrease, increase etc.

part 4 the gravitational acceleration can be determined from the slope of the graph of a vs. m/(M+m). What happens to the slope of the graph if you decrease the mass M of the glider?
