Question

Discuss the validity of extrapolating the acceleration value to an angle of 90°.

Answer 1

To find the acceleration when the angle of inclination is equal to 90 degrees, extrapolate the experimental values of acceleration versus angle of the incline. The acceleration at 90 degrees will equal 9.81 m/s/s, since this is the free-fall acceleration.

Answer 2

Answer:

Yes, it is validated to extrapolate the acceleration value to an angle of 90 degrees.

Explanation:

Assume the friction-less inclined plane. There exists a mathematical relationship between angle of incline and the object rolling in downward direction on friction-less inclined plan.

Acceleration of object = sinθ × g  

Here, θ=90 degrees so,

Acceleration of object = g = 9.8 m/s^2

Hence, it is validated to extrapolate the acceleration value to an angle of 90 degrees .
