A turntable is initially rotating a 1.50 rad/s and accelerates at 2.50 rad/s for 5.0s.
a) Calculate the final angular velocity in rad/s
b) Compute the angular displacement during the 5.0 s in radians and revolutions
Compute the Percent Errors between the Mag and Direction of the measured and the resultant component versions - How does the calculated displacement vector compare to the measured displacement vector?
