Velocity down different ramps
20 degrees 30 degrees 40 degrees
0.5 seconds after release 1.5 m/s 1.7 m/s 1.8 m/s
1.0 seconds after release 2.9 m/s 3.3 m/s 3.5 m/s
1.5 seconds after release 4.3m/s 4.9 m/s 5.1 m/s

the table indicates the velocity of a marble as it is released down 3 ramps. the 3 ramps have different angles. the same marble was used for each test.
what does the table suggest about the acceleration of the marble and why?
