<span>An impulse is the change in momentum. Momentum is mass times velocity.
Because the mass does not change, a change in velocity is what creates an impulse.
(14.0 m/s - 6.0 m/s) = 8.0 m/s.
(150 kg)x(8.0 m/s) = 1200 kgm/s.</span>
Answer:
a: $60.45
b: 20
Step-by-step explanation:
I did this on a test!
The equation is in standard form. Standard form is in this formula:
Ax + By = C
To convert a standard form to slope intercept form you first move Ax to the other side of the equation by inverse operations.
2x + 1.50y = 15
-2x -2x
1.50y = -2x + 15
You then divide B (From By) across the whole equation. (If you can't evenly divide make it a fraction)
1.50y = -2x + 15
1.50 1.50
y = -2/1.50x + 10
