= 1) A block of mass M = 5.0 kg initially at rest, is pushed across a horizontal surface by a force F = 20 N inclined at angle 6 = 30° with the horizontal. If the coefficient of kinetic friction between the block and the surface is 0.30, F M a) draw a free body diagram for the block. b) calculate the friction force c) determine the acceleration of the block d) if the block moved a 500 m during the period the force was in action, determine the speed of the block just before releiving the force. M = 10 kg 2) M 2 2M 3M The three blocks are pulled to the right by a force F = 650 N across a rough surface with coefficient of kinetic friction 0 25. a) show a free body diagram for each block. b) calculate the friction force on each block c) calculate the acceleration of the blocks d) the tension in cable 2 --- black M-1A ko calculate the tensions
