1. A block is at rest on a ramp. A person is pulling parallel to the ramp with a force $\vec{F_0}$, as shown. (Use the following values. $\theta = 30^\circ$, $m = 15.0$ kg, $\mu_s = 0.60$ a. Sketch and label all the forces acting on the block. (You may sketch on the image or use a free-body diagram.) b. What is the minimum force the person can pull without the block moving downhill? $\vec{F_0}$ m $\theta$

A $2.00-\mathrm{kg}$ block is held in equilibrium on an incline of angle $\theta=60.0^{\circ}$ by a horizontal force $\overrightarrow{\mathbf{F}}$ applied in the direction shown in Figure P4.52. If the coefficient of static friction between block and incline is $\mu_{1}=0.300$. determine (a) the minimum value of $\vec{F}$ and (b) the normal force exerted by the incline on the block.

A $2.00-\mathrm{kg}$ block is held in equilibrium on an incline of angle $\theta=60.0^{\circ}$ by a horizontal force $\overrightarrow{\mathbf{F}}$ applied in the direction shown in Figure P4.52. If the coefficient of static friction between block and incline is $\mu_{s}=0.300$, determine (a) the minimum value of $\overrightarrow{\mathbf{F}}$ and (b) the normal force exerted by the incline on the block.
A block of mass M = 2.00 kg is on a frictionless incline that makes an angle of θ = 30.0° with respect to the horizontal. A rope is connected to the block so that it can be pulled up parallel to the incline (see the figure below). a. Draw the free-body diagram of the block on the incline and list the forces when a tension is applied to keep the block at rest. b. Determine the magnitude of the normal force. c. Determine the magnitude of the tension assuming the block is moving at constant velocity. d. Determine the acceleration of the block when twice the tension (determined in question c) is applied to the block. e. Now imagine that the surface is not frictionless. If a tension of 20.0 N is applied to the rope, what would be the minimum value of the coefficient of static friction to keep the block at rest?
