## Homework Statement

Hi All,

The question That I am stuck on is:

**A packing crate has a nass 100kg is allowed to slide down on a ramp until it hit the ground. The friction resistance to motion is 240N. The length of the ramp is 10 m and thehieght of the crate from the ground just before it started to slide is 6m. Calculate the speed of the crate just before it hits the ground**

To be perfectly honest, I don't know where to start!! What would you work out first, don't want the answer just help on how to tackle the question - what needs to be worked out first?

## Homework Equations

g= 10N/Kg

I've found these equations while researching (I think they are relevant):

Speed = Distance / Time

Velocity = speed + Direction

Work = Force x Distance

## The Attempt at a Solution

Don't know where to start:surprised

Any advice would be most welcome
