Question

1. a major - league pitcher can give a 0.142 kg baseball a speed of 47 m/s. the magnitude of the baseballs magnitude is (a) 330.98 kgm/s (b) 6.674 kgm/s (c) 273.25 kgm/s (d) none of the above

Explanation:

Step1: Recall momentum formula

The formula for momentum $p$ is $p = mv$, where $m$ is mass and $v$ is velocity.

Step2: Substitute given values

Given $m = 0.142$ kg and $v=47$ m/s. Then $p=0.142\times47$.
$p = 6.674$ kg·m/s

Answer:

B. 6.674 kgm/s
