Homework Statement
The Egyptian's sled system had a rather high coefficient of static friction (0.7) but a much lower coefficient of kinetic friction (0.3) How much force is required to start a block moving on level ground?
We know the block is 1980 kg
and after that:
Assume that one person is able to apply 100N the block. Using this value, how many people does it take to pull a block at constance velocity along flat ground?
