Section: $q,$

The $90$ kg farmer tries to restrain the cow from escaping by wrapping the rope two turns around the tree trunk as shown in Figure $3.$ If the cow exerts a force of $1250$ N on the rope and the coefficients of static friction between the rope and the trunk is ${}_s=0\mathrm{.}15$ and between the man's shoes and the ground is ${}_s^{\text{'}}=0\mathrm{.}3,$ determine if the farmer can keep the cow from escaping.
