+15 pts. Answered. Force acting down the incline is mg sin 30 degree. Therefore both the blocks moves down with acceleration = g/2 = 0.50 g.
T = 15(9.81)N = 147.15 N r A v B •13–49. The 2-kg block B and 15-kg cylinder A are connected to a light cord that passes through a hole in the center of the smooth table. If the block travels along a circular path of radius , determine the speed of the block. r = 1.5m Free-Body Diagram:The free-body diagram of block B is shown in Fig. (a). The
8.11 A 3.0-kg mass starts from rest and slides a distance d down a frictionless 30 o incline, where it contacts an unstressed spring of negligible mass as in Figure P8.30. The mass slides an additional 0.20 m as it is brought momentarily to rest by compressing the spring ( k = 400 N/m).
A 20.0 kg box slides down a 12.0 m long incline at an angle of 3.0 degrees with the horizontal. A force of 50.0 N is applied to the box to try to pull it up the incline. A 2.0 kg breadbox on a frictionless incline of angle is connected, by a cord that runs over a pulley, to a light spring of spring constant , as...
8. Three situations involving a block with a weight of 10 N. and a string are shown in Figure 5.24. If the ramp remained at rest, the box would slide down the incline, but if the ramp is given a. 15. A box with a mass of 2.5 kg is initially at rest on a horizontal frictionless surface.
