K Tumblr ll 7:28 PM @ 1 0 36% Done 3 of 3 *21 From t=0 to t= 5.00 min, a man stands still, and from 1 = 5.00 min tot = 10.0 min, he walks briskly in a straight line at a constant speed of 2.20 m/s. What are (a) his average velocity Vvg and (b) his average acceleration a, in the time interval 2.00 min to 8.00 min? What are (c) v»y and (d) a, in the time interval 3.00 min to 9.00 min? (e) Sketch x versus t and v versus 1, and indicate how the answers to (a) through (d) can be obtained from the graphs. !!
