The coefficient of friction between the load and the flat-bed trailer is 0.40. While traveling at 100km/h, the driver makes an emergency stop and the truck skids to rest in 90m. Determine the velocity of the load relative to the trailer as it reaches the forward edge of the trailer.

Note: Initial distance between the load and the edge of the flat bed is 5m. I mean the load sits in the middle of the flat-bed and the distance from there to the edge of the trailer( rear glass of the truck) is 5m. Please help
