Question
3. A ball attached to a rope is spinning in a circle with a constant speed of 8m/s. If the length of the string is 0.4m, what is the acceleration a' (magnitude and direction) of the ball in the picture? 4. A ball is initially rolling 3m/s east along a table. It undergoes an acceleration of 0.4m/s² south for 2 seconds. What is the velocity of the ball after this acceleration? Write your answer as a tuple (vx, vy). 5. Consider these three vectors: A, B, and C. a. Draw these three vectors as a chain, and find their sum. b. Write the three vectors and their sum as tuples (vx, Vy). A = B = C= " → A + B + C = y A (0,2) X B C
