Two horizontal forces 218 n and 157 n are exerted in, Ask an Expert

Academics

Q1. 16.8-kg sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 85.6 N and is directed at an angle of 34 ° above horizontal. Establish the coefficient of kinetic friction.

Q2. Two horizontal forces, 218 N and 157 N, are exerted in opposite directions on a crate. What is the net horizontal force on the create? Be sure to indicate the direction of the net force. (Assume that the 218 N forces are in the positive direction.)
