This is biology. ( need asap and you will mark brainliest). momentum and collision math assignment. questions 1 - 8. ( i took a picture of questions 1 - 5). question 6) - two kids are roller skating. amy, with a mass of 55kg, is traveling forward at 3 m/s. jenny, who has a mass of 40kg, is traveling in the opposite direction at 5 m/s. they crash into each other and hold onto each other so that they move as one mass. how fast are they traveling? ( question 7) - jake is bowling with a 8kg bowling ball. he rolls the ball at 7 m/s, and it hits one stationary pin with a mass of 2kg. the pin goes flying forward at 12 m/s. how fast is the bowling ball now traveling ? ( question 8) - john has to hit a bottle with a ball to win a prize. he throws a 0.4 kg ball with a velocity of 18 m/s. it hits a 0.2kg bottle, and the bottle flies forward at 25m/s. how fast is the ball traveling after hitting the bottle? .

The answer to the first one is 1,350 kgm/s. The answer to the second is 100m/s. To the third is 2,200 kgm/s (I beleive I'm not quiet sure I'm finishing it up right now) To the fourth is 0.02624kgm/s. The fifth is 12.504.

Explanation:

And I know she's gonna mark you off if you don't show your work so here if you want you can just copy and past it.

The speed when Sam leaves the jump is v=18m/s. The momentum when he leaves is p? The linear momentum of a body is equal to the mass multiplied by its velocity. It is a vector quantity where it is directed along with the velocity of the body. P=75 KG times 18 m/s which equals to 1,350 KG m/s. And the formula is p= m*v.  

And I'm working on 6th through 8th, but when I'm done I'll tell you if you want.

the intolerable acts were punitive laws passed by the british parliament in 1774 after the boston tea party. in great britain, these laws were referred to as the coercive acts.

answer:

it caused mass african migration, african populations to grow, african empires to topple, and racism against slaves to emerge.
