Question 8 (1 point) Listen For the next three questions, consider the motion diagram of a ball on a string as it moves with constant speed in a circle: If the radius of the circle is 0.05 m and it takes 0.3 s for the ball to complete one revolution, then what is the speed of the ball? Round your answer to the nearest tenths place. Your Answer: Answer unitsQuestion 9 (1 point) Listen Instants in time are numbered. At time to, in which direction does the vector Ave point? Construct Ave by subtracting vs from v7 and drawing the resultant from the location of the ball at to, i.e. Av6 =V7 -V5. 090 0 0 0 0 0Question 10 (1 point) Listen Instants in time are numbered. At time to, in which direction does the acceleration vector point? -(9) : Be carefule then V5 - V5 D VG = VJ - V5 Answer Third option is correct . and Acceleration DV = DVE to 9 & DVG Same direction of acceleration as direction of Change in Webcity . Acceleration. Answer ( third option )
