Review: Quiz L #1 - 3 (Monday 14th)
Last day for extra credit $ (Lab Fee)
Journal: What is a vector and how do you add them together?
Put in Scientific Notation:
1. 4500 = 2. 76,000,000 =
3. .0000005 =
4. 5000 x10-7 =
Convert: 5. 4000 km/hr to cm/s =
6. 50 m2 to mm2 =
(7 & 8) Put into rectangular form : 7. 100 ∟300
X = ________ , y = ____________
8. 100 ∟2000
X = ________ , y = ____________
9. Add vectors then polar form:
x1 = 50, y1 = -70
x2 = -40, y2 = 20
x3 = -30, y3 = 100
x = ______ y = ________
à à __________ ∟_____0
10. You went east @ 100km/hr due for 30mins. Then head south @ 200km/hr for 1.0 hr. Then you head north @ 20km/hr for 90mins. Finally, you head west at 100 km/hr for 1.5 hrs.
1. 4500 = 4.5 x103 2. 76,000,000 = 7.6 x107 3. .0000005 = 5 x10-7 4. 5000 x10-7 = 5 x10-4 Convert: 5. 4000 km/hr to cm/s = _____________________
4000km/hr (1000m/1km) (1 hr/3600s) = 1111
8. 50 m2 to mm2 = _____________________
50m2 (1,000,000 mm2 / m2 ) = 50,000,000 mm2
(7 & 8) Put into rectangular form : 7. 100 ∟300
X = 50, y = 86.6
8. 100 ∟2000
X = -34.2, y = 94.0
9. Put into rectangular then polar form:
x1 = 50, y1 = -70
x2 = -40, y2 = 20
x3 = -30, y3 = 100
X = -20, y = 50
à à 53.9∟112o
10. You went east @ 100km/hr due for 30mins. Then head south @ 200km/hr for 1.0 hr. Then you head north @ 20km/hr for 90mins. Finally, you head west at 100 km/hr for 1.5 hrs.
