Question

Physics

1. The angle of an airplane propeller makes with the horizontalas a function of time is given by θ=(125rad/s)t+(42.5rad/s^2)t^2.estimate the instantaneous angular velocity at t=0.00s bycalculating the average angular velocity from t=0.00s tot=0.010s

A. Estimate the angular speed at t = 0 by calculating theaverage angular speed between ti = 0 and tf = 0s.

B. Estimate the angular speed at t = 1.00 by calculating theaverage angular speed between ti = 1.00 and tf = 1.01s.

C. Estimate the angular speed at t = 2.00 by calculating theaverage angular speed between ti = 2.00 and tf = 2.01s.

D. Based on the above calculations, is the angular accelerationof the propeller negative, zero, or positive? Explain.

E. Calculate the average angular acceleration from t = 0.00 to1.00s and from t = 1.00 to 2.00s.

F. Compare the angular acceleration calculated in E with thevalue of angular acceleration observed in the appropriatecoefficient of the original equation for angle as a function oftime. If they are not the same, explain why this might be?
