Question

The graph below plots velocity vs. time for an object moving along a straight path. v (m/s) 24 18 12 6 0 7 14 21 t(s) 28 -6 -12 -18 -24 (a) What is the average acceleration of the object during the following time intervals? (Enter your answers in m/s². Indicate the direction with the signs of your answers.) (i) 0 s to 7.00 s m/s² (ii) 7.00 s to 21.0 s m/s² (iii) 0 s to 28.0 s m/s² (b) What is its instantaneous acceleration at each of the following times? (Enter your answers in m/s². Indicate the direction with the signs of your answers.) (i) 6.00 s m/s² (ii) 14.0 s m/s² (iii) 24.0 s
