2 Your answer is partially correct. Try again. In the figure, a slab of mass m, = 40 kg rests on a frictionless floor, and a block of mass m, = 9 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force F of magnitude 102 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab? u = 0- (a) Number T-7.4 -7.4 Units m/s^2 (b) Number i+ Units m/s^2 -0.88 Click if you would like to Show Work for this question: Open Show Work SHOW HINT LINK TO TEXT LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM VIDEO MINI-LECTURE 10:50 PM search ENG 4/4/2021 ond 111Pgup) pri sc DOUSE insert dele home break 13) 23 bac 3 5. 4 R.

In the given picture, a bar with length L and negligible weight is laid on the wall. If the coefficient of friction between the bar and the wall is 0.15, and the friction between the pin C and the bar is negligible. Find the interval for the fraction L/a in which the system is in balance.
3. Two blocks, mı = 9 kg and mɔ = 15 kg, are connected by a light string that passes over a frictionless pulley as shown in the figure. The first block lies on a horizontal surface and is connected to a spring with 45 N/m force constant. The system is released from rest when the spring is at equilibrium (unstretched). If the kinetic friction between mị and the surface is 0.20, calculate: (a) the distance h which the hanging block falls before coming to rest. (b) the work done by the spring on mị (c) the work done by the string on m || k
A heavy cabinet with a mass of 135kg is transported on the truck platform. Assume that the friction between the cabinet and the platform is so great that the cabinet cannot slip, but can instead tip over. The dimensions shown in the cabinet figure are hG = 1.8m, xG = 1.0m and b = 3.4m. How high can the maximum acceleration of the truck to the right be without the cabinet tipping over? What is the angular acceleration of the cabinet in the situation under consideration

Figure 2 В A Block A is hanging from a massless string which runs over a massless and frictionless pulley and connects to Block B. Block B slides over an inclined plane with ordinary kinetic friction. The plane under block B is inclined at an angle theta = 0 away from vertical. The other side of Block B is connected to another massless string which runs over another massless and frictionless pulley to connect to Cart C. Cart C rolls without friction over a plane which is inclined at an angle of phi = y away from vertical. C

Show complete solutions. Please draw the figure or the illustrations. Problem:Two horses are pulling a barge with mass 2000 kg along a canal, as shown in the Figure. The cable connected to the first horse makes an angle of 30o with respect to the direction of the canal, while the cable connected to the second horse makes an angle of 45.0o. Find the initial acceleration of the barge, starting at rest, if each horse exerts a force of magnitude 600 N on the barge. Ignore forces of resistance on the barge.
Two blocks of mass m = 2.00 kg are connected by a vertical string of negligible mass and unknown tension Tm are hanging vertically. The higher one of these two masses is directly attached to another string of negligible mass and unknown tension T that goes over a frictionless pulley of negligible mass and is connected to a third block of mass M = 6.00 kg. The heavier block is free to slide on an incline (of angle 0 = 30.0° w.r.t. the horizontal) with coefficients of kinetic friction of µA = 0.120 and static friction µ,=0.150 between the block and the incline. The system is released from rest. !! M a) Please perform a test to determine which way the system would like to move in the absence of any friction. b) Please perform a test to determine whether the system will be able to overcome the maximum of static friction and be able to move, or remain at rest instead. c) Determine the magnitude of the normal force N exerted on the third block by the incline. d) Determine BOTH the magnitude…
