A block with a mass of 4 kg is pulled across a horizontal surface at constant speed by a horizontally directed rope. The coefficient of kinetic friction between the block and the surface is ÎĽk = 0.2. What is the acceleration (in m/s2) of the block if the tension in the rope is 12 N

A $2 \mathrm{~kg}$ block is placed over a $4 \mathrm{~kg}$ block and both are placed on a smooth horizontal surface. The coefficient of friction between the blocks is 0 -20. Find the acceleration of the two blocks if a horizontal force of $12 \mathrm{~N}$ is applied to (a) the upper block, (b) the lower block. Take $g=10 \mathrm{~m} / \mathrm{s}^{2}$
A $2.5 \mathrm{~kg}$ block is initially at rest on a horizontal surface. A $6.0 \mathrm{~N}$ horizontal force and a vertical force $\vec{P}$ are applied to the block as shown in Fig. 6-45. The coefficients of friction for the block and surface are $\mu^{\text {stat }}$ $=0.40$ and $\mu^{\mathrm{kin}}=0.25 .$ Determine the magnitude and direction of the frictional force acting on the block if the magnitude of $\vec{P}$ is (a) $8.0 \mathrm{~N}$, (b) $10 \mathrm{~N}$, and (c) $12 \mathrm{~N}$.
