## Homework Statement

A cork ball of mass 100 g at rest is released from a height of 8.5 m above the launch

point of a 300 g dart which is projected vertically upwards with an initial velocity of

12 m s–1. Upon impact, the cork ball and the dart stick together. Calculate their velocity

immediately after the collision.

## Homework Equations

m

_{1}v

_{1}=m

_{2}v

_{2}

v=u+at

V

^{2}=u

^{2}+2as

## The Attempt at a Solution

*m trying to work out how to do this. I am thinking put two equations equal to each other in respect to time, as time will be the samwe both of them when they collide, I am just having trouble finding out which equations to use*

Sorry in the title i say elastic when its inelastic
