Momentum and Our Dynamics Test

Okay this is Benofschool and this is the scribe for today.

We got our last test back and I am disappointed in my mark =(
Anyways here are the answers:

1.
2.
3. F_g = 103 N

4. F_|| = 11226 N

5. a= 1718.75 m/s² then use it to find F_resistance = -51.6 N

6a) F_n = 4410 N

b) F_a = 1500N

7a) F_|| = 94.5 N

b) F_n = 112.6 N then use it to find F_f = 24.7 N

c) F_net = 69.7 N

d) a = 4.65 m/s²


After correcting the test that I did horribly on we corrected chapter 9.1 study guide on Impulse and Change in Momentum

The blanks are filled in this order:

Momentum and Impulse
1) velocity 2) mass 3) mass 4) velocity 5) vector 6) the same as 7) p=mv 8) momentum

9) mass 10) velocity 11) kilogram x metre/ second 12) force 13) time interval 14) the same as

15) newton x second 16) momentum 17) impulse-momentum 16) second (2nd)

We were not required to do Angular Momentum

So then we received a 2 page booklet on Impulse and Momentum and I think should be done for tomorrow for homework.

This is the scribe for today and the next scribe will be Tony
