Question

1) Calculate the difference between the given expermintal value of the cart's acceleration and the theoretical value.

2) Calculate the propagated error in the difference between the experiment and theoretical values of the cart's acceleration. through only approximately correct, assume the propagated percent error in the theoretical accleration is the same as the perecent error of the angle of incination.

3) write two sentence to explain whether the experimental and theoretical acceleration agree within the limits of expermental error.

4) The theoritical prediciton for the cart's acceleration makes one or two simplifying assumptions. What is at least on of these assumptions?

Explanation / Answer

(a) a=g sin (12) = 9,81* sin (12) = 2,039 m/s2

Delta acceleration= 2.039- 1.89 = 0.149 m/s2

(b) a=at - ae = 0.2 - 0.08= 0,12

(c) the theroical and the experimental acceleration agree within the limits of the error, because the theorical acceleration is 2.039 + - 0.2= 1,919; and the experimental acceleration is 1,89 +- 0,08= 1,97, an there is an intersection between that two values.

(d) the theorical acceleration is not considering the friction force hat would decrease the value of the actual theorical acceleration
