if a tennis ball has a velocity of 18 m/s and a momentum of 1.06 kg·m/s, what is the mass of the tennis ball…

Answer:

59 grams

Explanation:

Step1: Recall momentum formula

$p = mv$ (where $p$ is momentum, $m$ is mass, $v$ is velocity)

Step2: Rearrange for mass

$m=\frac{p}{v}$

Step3: Substitute values

$m=\frac{1.06\ kg\cdot m/s}{18\ m/s}\approx0.0589\ kg$

Step4: Convert to grams

$0.0589\ kg\times1000 = 58.9\ g$

Step5: Round to two - sig figs

$59\ g$
