<span>x2 + 9x + 20
Factor the equation
(x+5) * (x+4)
x = -5
x = -4

<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>
Im pretty sure it would be $60. If im wrong im sorryyyyy
