Figure 1: Block on incline. 2, A block of mass m = 5 kg is subject to a force of magnitude 20 N that makes an angle of p20 with the (frictionless) inclined plane of contact. The plane itself is inclined θ = 300 with the horizontal. (a) What is the acceleration of the block along the incline? (b) If the block begins at rest, in what direction will it move subsequently (i.e., up or down the incline)? (c) If...

The critical angle is the largest angle for which the gravitational force does not yet cause the block to move. Finding the angle is a problem in which we deal with the block as a particle in equilibrium. Analyze Because the block is an inclined surface, the normal force perpendicular to the surface does not balance the downward force of gravity. The normal force and the force of gravity produce a net force that tends to slide the block down...

2. 2/10 points Previous Answers SerPSE10 5.AE.011. My Notes Experimental Determination of H's and The following is a simple method of measuring coefficients of friction. Suppose a block is placed on a rough surface inclined relative to the horizontal as shown in the figure. The incline angle is increased until the block starts to move. Show that you can obtain H by measuring the critical angle e, at which this slipping just occurs. The external forces exerted on a block...

A 0.42 2 kg block is sliding down a rough surface that is inclined 13.6 degrees with respect to the horizontal. The coefficient of kinetic friction for the surface is 0.162. A force, directly opposing the blogs motion, sufficient to cause it to slide with constant velocity, is being exerted on the Block while it moves. a) Draw a free body diagram for the block and appropriately tilt/rotate its axes. b) Write Newton's laws of motion equations for the x...
