Question

a ball has 2kg*m/s of momentum when thrown with a velocity of 8 m/s outwards. find the mass of the ball.

Explanation:

Step1: Recall momentum formula

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

Step2: Rearrange formula for mass

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

Step3: Substitute values

$m=\frac{2\ kg\cdot m/s}{8\ m/s}= 0.25\ kg$

Answer:

0.25 kg
