Pls. answer number 4 only. And provide complete solution and right answer. Lesson 1: Force and MotionInstruction; Show your complete and neat solution. Identify your final answer in the solution.See answer sheet format.1. A force of 20 N acts upon a body whose weight is 8 N. What is the mass of the body?What is its acceleration?2. Two masses of 8 kg and 12 kg are tied to each end of a string passing over a masslessand frictionless pulley. Find the resulting acceleration of each mass.3. A 1000-kg mass elevator has an acceleration of 1%². What is the tension in thesupporting cable if the elevator is a) ascending and b) descending?4. A 5 kg block resting on a frictionless inclined plane with an inclination angle of 20° isattached to another 5 kg block that hangs freely by a string passing over a massless,frictionless pulley. What is the resulting acceleration of the two blocks?5. A block weighing 60 N rests on a horizontal floor. a) What is the minimum force thatwill make the block move if the coefficient of static friction is 0.20? b) What is theminimum force that will keep the block moving at uniform speed once it starts movingif the coefficient of kinetic friction is 0.10?6. Blocks A and B have weigh of 44 N and 22 N, respectively (see figure below).a) Find the minimum weight of block C thatmust be placed on top of block A to keepit from sliding. Take the coefficient ofstatic friction between A and the table topto be 0.20.b) Block C is suddenly lifted off A. Find theresulting acceleration of the system if thecoefficient of kinetic friction between A and the table is 0.15.7. A force of 150 N pushes a box. Starting from rest, the box achieves a velocity of 1.50"% in 2.5 s. Find the coefficient of sliding friction between the box and the floor.
