Physics 121 Appl. Newton's Laws Quiz Friday, May 15,2022 SHOW ALL SOLUTION ON THE PLAIN SHEETS SUPPLIED. NO SOLUTION ON THIS TEST PAPER IF = 0 for equilibrium state IF - ma for accelerated state 1) A block of mass M = 4.0 kg initially at rest, is pushed across a horizontal surface by a force F-20N inclined at angle - 30" with the horizontal. If the coefficient of kinetic friction between the block and the surface is 0.30, M a 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 2M 3M The three blocks are pulled to the right by a force F - 600 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 3) In the figure shown, if the mass of the hanging block M = 12 kg, calculate the tensions T1, T2 and T3 in the strings T3 T2 60° 40° T1 M
