Chapter 6, Problem 3PCE
A 1.8-kg block slides on a horizontal surface with a speed of v = 0.80 m/s and an acceleration of magnitude a = 2.8 m/s2 , as shown in Figure 6-30. (a) What is the coefficient of kinetic friction between the block and the surface? (b) When the speed of the block slows to 0.40 m/s, is the magnitude of the acceleration greater than, less than, or equal to 2.8 m/s2? Explain.

If the 50-kg crate starts from rest and attains a speed of
6 m/s when it has traveled a distance of 15 m, determine the
force P acting on the crate. The coefficient of kinetic friction
between the crate and the ground is μ = 0.3.
A 4.10 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 40.0 N. Figure 6-30 gives the block’s speed v versus time t as the block moves along an x axis on the floor. The scale of the figure’s vertical axis is set by vs 5.0 m/s. What is the coefficient of kinetic friction between the block and the floor?
Two boxes are connected by a rope that passes over a pulley (Figure 6-31). Box #1 is on a ramp inclined at 35° to the horizontal, and the coefficient of kinetic friction between the box and ramp is 0.54. The masses of the boxes are m1 5 2.5 kg and m2 5 5.5 kg. Neglecting the motion of the pulley and assuming that the velocity of each box is in the same direction as its acceleration, what is the magnitude of the acceleration of the boxes?
