Find the mean time for each ramp length

Mean 3.6s

Find the ball's acceleration for each mean time using the equation below where D is distance or ramp length and T is time
Acceleration=2D/T^2

1.5m(Distance) Use 3.6

a = 2 (1.5)/3.6^2

To find the acceleration for a ramp length of 1.5m using the mean time of 3.6 seconds, we can substitute the values into the equation:

Acceleration = 2 * Distance / Time^2

Acceleration = 2 * 1.5m / (3.6s)^2

First, let's calculate the time squared:
Time^2 = 3.6s * 3.6s = 12.96s^2

Now, we can substitute the values back into the equation:
Acceleration = 2 * 1.5m / 12.96s^2

Dividing the distance by the time squared:
Acceleration = 0.231m / s^2

Therefore, the acceleration for a ramp length of 1.5m based on the mean time of 3.6 seconds is 0.231 m/s^2.
