Answer:
sure if im able, with what?
Step-by-step explanation:
- Answer:
answer is (2,8)
Step-by-step explanation:
b coordinate is (2,8)
Answer:
angle b = 79
Step-by-step explanation:
Angle b = 79 because they alternate exterior angles. Alternate exterior angles are equal when the lines are parallel.
Initially, Ball A of 10 kg will have velocity x, while Ball B of 30 kg has velocity -10 m/s.
After collision, Ball A will have a velocity of -30 m/s, while Ball B will have velocity 10 m/s. We assume their masses do not change.
(10 kg)(x m/s) + (30 kg)(-10 m/s) = (10 kg)(-30 m/s) + (30 kg)(10 m/s)
10x - 300 = -300 + 300
x = 30 m/s (to the right)
