Question

the chart shows masses and velocities of four objects. which lists the objects in order, from least to greatest momentum? motion of four objects object mass (kg) velocity (m/s) w 12 5 x 15 8 y 18 2 z 28 10 o w, x, y, z o z, y, x, w o z, x, w, y o y, w, x, z

Explanation:

Step1: Recall momentum formula

Momentum $p = mv$, where $m$ is mass and $v$ is velocity.

Step2: Calculate momentum of object W

$p_W=12\times5 = 60$ kg·m/s

Step3: Calculate momentum of object X

$p_X=15\times8=120$ kg·m/s

Step4: Calculate momentum of object Y

$p_Y=18\times2 = 36$ kg·m/s

Step5: Calculate momentum of object Z

$p_Z=28\times10=280$ kg·m/s

Step6: Arrange in ascending order

$p_Y < p_W < p_X < p_Z$

Answer:

Y, W, X, Z
