I. Traffic Accident #1: It is crash-test-dummy Ed's first day on the job. He (and his 50-kg mass) gets to try out the new 1,200-kg Porsche 911. Lucky Ed! He has to drive it into a brick wall. Unlucky Ed! But it's his job, so he does it.
The Porsche and Ed are moving 30 m/s when they collide with the wall, with an impulse time of 0.5 s.

1. What is the magnitude of their initial momentum? (4 points)

2. What is the magnitude of their final momentum? (3 points)

3. What is the magnitude of the impulse of the collision? (3 points)

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
