NOTE: The net force equation is applied to differentdimensions independently.A horizontal force of 85 N is required to pull achild in a sled at constant speed over dry snow toovercome the force of friction. The child <strong>and</strong> sledhave a combined mass of 52 kg. Calculate thecoefficient of kinetic friction between the sled <strong>and</strong>the snow. (0.17)12
1. A 62 kg crate is pulled at a constant velocity with anapplied force of 337 N.a. Calculate the force of friction.b. Calculate the normal force on the crate.c. Calculate the coefficient of kinetic friction.13
