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?

2. Relevant 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

3. The attempt at a solution

Don't know where to start:surprised

Any advice would be most welcome
