there's a 150 lb person on a rolling chair and moves in a circle when a motor with a rope attached on it is hooked up to the chair.(adsbygoogle = window.adsbygoogle || []).push({});

If the radius of the circle is 7 ft, how much horsepower would the motor need to have to move the person at 1 m/s given that the friction coefficent is about 0.50.

Can someone give me an idea on how I can try to find how many horsepowers it would take? Thanks
