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? .
