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:                  

54000 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. Speed

 

 

 

  1. Displacement

 

 

 

 

  1. Velocity

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 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:                  

54000 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     53.9112o

 

 

 

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. Speed    95.6 m/s

 

 

 

  1. Displacement   197 239.5o

 

 

 

 

  1. Velocity   43.8 239.5o
