A worker pushes horizontally on a 35 kg crate with a force of magnitude 110 N. The coefficient of static friction between the crate and the floor is 0.37. (a) What is the value of ƒ s , max under the circumstances? (b) Does the crate move? (c) What is the frictional force on the crate from the floor? (d) Suppose, next, that a second worker pulls directly upward on the crate to help out. What is the least vertical pull that will allow the first worker’s 110 N push to move the crate? (e) If, instead, the second worker pulls horizontally to help out, what is the least pull that will get the crate moving?

In the first figure here, a sled is held on an inclined plane by a cord pulling directly up the plane. The sled is to be on
the verge of moving up the plane. In the second figure, the magnitude F required of the cord's force on the sled is
plotted versus the coefficient of static friction u, between sled and plane: F1 = 1.69 N, F2 = 5.38 N, and µ2 = 0.543. At
what angle 0 is the plane inclined?

You are pushing a box, apply Fa = 90 N. The box's mass is 25 kg. The coefficients of friction are μs =0.60 and μk = 0.4. The box was stationary when you began pushing. Calculate the frictional force magnitude exerted on the box by the floor
