Please Help! (Force Problems) Pulling horizontally on a rope moves a block with a total mass of 175.0 kg. If the coefficient of static friction between the block and the ground/slope is 0.12, what force must be applied to the rope to start the sled moving? If a second identical block is tied to the first block, and both are pulled with a force of 250.0 N, what acceleration will both experience, if the coefficient of kinetic friction is 0.10? Please help! I do not really understand how to approach this problem because I am having understanding forces.
