Vector description of motion around a bend
Thanks for your help. When I draw it out I see an angle that is 45 degrees south of west, which makes sense to me. I'm really glad to hear you say the 41 degrees is a typo, but what about the magnitude of average acceleration of 5.12m/s sq. That has to be a typo too right? Since the question...- ianperez

Vector description of motion around a bend
That sounds like a lot of fun, but I'm certain that's beyond my present day abilities. Thanks though- ianperez

Vector description of motion around a bend
Homework Statement A car, initially going eastward, rounds a 90 degree bend and ends up heading southward. If the speedometer reading remains constant, what is the direction of a car's average acceleration vector? -So i know the speed remains constant. Homework Equations average...- ianperez

How Is Average Acceleration Calculated for a Clock's Hour Hand Movement?
I got it! Thank you! The circumference is 4.8π so the velocity is 4.8π/12hrs=1.26cm/he Vi= 1.26i + 0j Vf = -1.26i + 0j Acceleration = (change in velocity of a point on the tip) / elapsed time A= -1.26-1.26 / 6hrs = -0.42cm/hr- ianperez

How Is Average Acceleration Calculated for a Clock's Hour Hand Movement?
Homework Statement What are the average velocity and average acceleration of the tip of the 2.4-cm-long hour hand of a clock in the interval from 12p.m. to 6p.m. I'm given the displacement which is 4.8 cm. I know the motion takes six hours I set my x-axis at three-o-clock and my y-axis at...- ianperez
