Question

Arysha enjoys playing lacrosse on the school team. Suppose Arysha throws a lacrosse ball with force of 6 N, and the resulting acceleration is 43 m/s2. What is the mass of the lacrosse ball?

Answer 1

Given that,

Force with which Arysha throws a lacrosse ball, F = 6 N

The resulting acceleration of the ball, $a=43\ m/s^2$

To find,

We need to find the mass of the lacrosse ball. It is a case of Newton's law.

Solution,

The net force is given by :

F = ma

m is mass of the lacrosse ball

$m=\dfrac{F}{a}\\\\m=\dfrac{6}{43}\\\\m=0.139\ kg$

So, the mass of the lacrosse ball is 0.139 kg.
