The velocity of a 150 kg cart changes from 6.0 m/s to 14.0 m/s. What is the magnitude of the impulse that acted on it?

tatuchka [14]

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.

kwasi thought of a number, multiplied it by7/2 and added 16 to the results.if the final answer was 30.what number did he think o

ziro4ka [17]

Answer:

Step-by-step explanation:

represent the number he thought of with x

$\frac{7}{2} x + 16 = 30$

multiply through with the LCM which is 2
$2 \times \frac{7}{2}x + 16 \times 2 = 30 \times 2$
$7x + 32 = 60$
$7x = 60 - 32$
$7x = 28$
$\frac{7x}{7} = \frac{28}{7}$
$x = 4$

Find the value of X.

pychu [463]

Answer:

Solution,

Theorem:

The angle bisector theorem states that if a ray bisects an angle of a triangle,then it divides the opposite side into two segments that are proportional to other two sides.

By the theorem,

$\frac{24}{9x - 9} = \frac{32}{6x + 6} \\ or \: 24(6x + 6) = 32(9x - 9) \\ or \: 144x + 144 = 288x - 288 \\ or \: 144x - 288x = - 288 - 144 \\ or \: - 144x = - 432 \\ or \: x = \frac{ - 432}{ - 144} \\ x = 3$
