8:43 PM 0.9KB/s O LTE 78 E mfewpe - 11 - 2020 bodies, if a force of 1N, parallel to the surface is applied to m2? 13) A short commutator train consists of a locomotive and two cars. The mass of the locomotive is 6000kg and that of each car is 2000kg. The train pulls away from a station with an acceleration of 0.5ms -2. Determine the horizontal pulling force that the locomotive wheels exert on the track, the tension between the couplings joining the two cars and the tension between the couplings joining the two cars. 14) A block mı = 0.2kg to which a light inextensible string is attached rests on a smooth horizontal surface. The string passes over a light frictionless pulley fixed at the end of the table. Another block of mass m2 = 0.1kg is attached to the free end of the string and hangs freely vertically. Determine the acceleration of the system and the tension in the string. 15) A block mj = 0.2kg is placed on a smooth inclined plane inclined at an angle of 30° with the horizontal. To this mass is attached a string which after passing over a smooth frictionless pulley at the top of the plane freely supports another mass m2 = 0.105kg hanging vertically. Determine the acceleration of the system and the tension in the string and the distance m2 descends from rest in 2s. 16) A penguin of mass 15kg is weighed on a moving elevator. What is the mass recorded by the weighing machine when the elevator a) is stationary b) ascends with a constant velocity of 2 ms 2ms - d) ascends with a constant acceleration of 2ms -2 e) descends with a constant acceleration of 2ms with a constant deceleration of 2ms -2 g) descends with a constant deceleration of 2ms -2 h) cord snaps? 17) From a stationary tank of mass 1,25,000kg a small shell of mass 25kg is fired with a muzzle speed of 1000m/s. Determine its velocity of recoil. c) descends with a constant velocity of -2 f) ascends
