Assume the w before the rough area is so slippery that you can re any friction between the skis and the snow If the frictional force exerted by the snow in the rough area is 40 N, how far across the rough area does the skier travel before stopping?

Explanation / Answer

Given that

mass m=40 kg

speed v=31km/h=31*5/18=8.6 m/s

force F=40 N

basing on the concept of lwas of motion

now we find the distance

force F=mv^2/2X

40=40*8.6^2/2X

distance X=36.98 m

therefore the distance x=36.98 m
