A lab handout for Speed.doc – Average Speed (official unit experiment)

Part a ) should be between 300 and 500 m/s written with 3 sig figs; Part b) should be between 50,000 and 90,000 m/s written with 2 sig fig

Test-Prep:

Review vector asst set 1, 4E – 2A = 138 meters at 186 degrees (equilibrant is opposite; speed = 140 m / time; vel = 138 m / time at 186 degrees)

Review vector asst set 1, 2A – 4E

a)160 km

b)158 km @ N25°E

c) speed = 16.0 km/hr

d) vel = 15.8 km/hr @ N25°E

e) equil = 158 km @ S25°W OR 245°
