the Newpanent is 6) A student runs at 4.5 m/s [250 S of W] for 3.0 minutes. Then he jogs at 3.5 m/s [350 S of E] for 4.1 minutes. a) What was his average speed? + = 2465 + = 1 1265 v = d V = 3. 92 +2 = 1805 V= 3.9 d= 810+ 861 V = 1671 426 1= 1671 the avg speed is 3.9 mis b) What was his final displacement? V = 14.5 ) cos ( 25 ) V = 3. 5 ( OS / 35 ) V = 1.1 V = 2.9 V= (4.5 ) sin 25 V = 3.5 sin ( 35 ) V = 1.9 V = 2. 0 V+= - 2.2. 9 = 2.2 mrs vt = - 409
