- A sled is on a horizontal surface and a rope with tension T is pulling on it at an angle e above the horizontal. The sled had mass M and does not move due to the frictional force. In this case the coefficient of friction is ug. In terms of the variables given and g, what is the magnitude of the frictional force in this case? Select one: O a. Tcose O b. H, Mgsin0 Ос. Tsin® O d. H, MgcoseTwo blocks are joined by an inextensible cable as shown. If the system is released from rest, determine the velocity of block A after it has moved 2 m. Assume that the coefficient of kinetic friction between block A and the plane is 0.25 and that the pulley is weightdess and frictionless. 200 kg ㄱ 300 kg A BIn the figure below, the coefficient of kinetic friction between the block and Inclined plane is 0.27 and angle 0 is 59°, What is the block's acceleration (magnitude and direction) assuming the following conditions? (a) It is sliding down the slope. m/s2 O down the slope O up the slope (b) It has been given an upward shove and is still sliding up the slope. m/s2 O down the slope O up the slope
