Set a frictionless incline at various measured angles then determine the acceleration of a block by measuring the time it takes to increase from an initial speed to a final speed.If the angle is 20 and the initial speed is 0.68m/s and final speed is 2.43m/s and the time is 0.51s how do I find the acceleration.

To find the acceleration of the block, we can use the following equation:

a = (vf - vi) / t

where:
a = acceleration
vf = final speed
vi = initial speed
t = time

Given:
vi = 0.68 m/s
vf = 2.43 m/s
t = 0.51 s

Substituting these values into the equation:

a = (2.43 - 0.68) / 0.51

Now we can calculate the acceleration:

a = 4.75 / 0.51
a ≈ 9.31 m/s²

Therefore, the acceleration of the block is approximately 9.31 m/s².
