Question

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

Answer 1

Answer:

$\large \boxed{\text{0.25 kg}}$

Explanation:

We can use the formula for momentum to calculate the mass.

$\begin{array}{rcl}p & = & mv\\2 & = & m \times 8\\m & = & \dfrac{2}{8}\\\\& = & \textbf{0.25 kg}\\\end{array}\\\text{The mass of the ball is \large \boxed{\textbf{0.25 kg}} }$

Answer 2

0.25 kg

Explanation:

0.25kg

P=Mv

2=mx8

M=2/8

=0.25kg
