Question

In a lacrosse game a ball is thrown with a force of 2000 N. The throwing force acted for 0.8

seconds. If the ball had a change in velocity, Av, of 50 m/s, what is the mass of the ball?

Answer 1

Mass, m = 32 kg

Step-by-step explanation:

Given that,

Force, F = 2000 N

The change in velocity, (v-u) = 50 m/s

Time, t = 0.8 s

We need to find the mass of the ball. The net force acting on an object is given by :

F = ma

Where a is acceleration

`F=(m(v-u))/(t)\\\\m=(Ft)/((v-u))\\\\m=(2000* 0.8)/(50)\\\\m=32\ kg`

So, the mass of the ball is 32 kg.
