Question

A white pool ball of mass 200g is hit with a velocity of 1.6ms^-1
and collides with a stationary
striped ball of the same mass.
If the striped ball moves off with a velocity of 1.9ms^-1
then calculate or find:
a) Velocity of the white ball after the collision

Answer 1

Answer:

your option is D

Explanation:

M=200gm

∆v=0.01m/s

∆n=h\4π×1/5×0.01=2.62×10-³² m

Answer 2

Answer:

First we'll write both their masses and then u and v

Secondly, we'll use the formula: $m_{1} u_{1} + m_{2} u_{2} = m_{1} v_{1} + m_{2} v_{2}$

So by this method we'll get the answer,..

I am getting the answer as 1.4m/s
