A ball on a string swings in a horizontal circle as shown below. The ball has a mass of 0.2 kg, and the string is 0.6 meters long. (The ball is going into the page at the moment shown; the axis of the rotation is the dotted line in the picture) a) ] Draw a force diagram for the ball. b) ] Use Newton's 2nd Law to calculate the acceleration of the ball. Show your work. $F = ma$ $0.6 = 0.2a$ $a = 3$ ) Using the acceleration found in part b), calculate the angular frequency $\omega$ of the ball. What is the direction of $\omega$? $\rightarrow$ down

Problem 6.83 - Enhanced - with Feedback Part A On an essentially frictionless, horizontal ice rink, a skater moving at 6.0 m/s encounters a rough patch that reduces her speed by 43% due to a friction force that is 26% of her weight. Use the work-energy theorem to find the length of this rough patch. Express your answer in meters. s =
