A block is initially moving to the right on a level, frictionless surface. A hand exerts aconstant horizontal force on the block that causes the block to slow down (stage 1), turnaround, then move in the opposite direction while speeding up (stage 2).1. Complete the table below. Draw arrows to indicate relevant directions, and take thepositive x-direction to the right.DisplacementForce by handWork doneDirectionSignDirectionSignSignStage 1Stage 2

**ALL NECESSARY INFORMATION IS GIVEN, A spool rests on a horizontal, frictionless surface and you are looking at it from the top view (appears as a circle).In the following questions, the spool is pulled by tension forces that are applied at various locations, directions, and radii.To solve each problem, draw the spool as a circle on a piece of paper and then draw the given tension vectors.REMEMBER that the direction UPWARD points to the TOP of the page and DOWNWARD points to the BOTTOM of the page.The resulting TORQUE will be either OUT OF the page (CCW motion, POSITIVE torque) or INTO the page (CW motion, NEGATIVE torque).A rope of tension 2T applies a force at radius 3R on the spool. It is located at 12 o'clock and pulls to the left.What is the resulting torque in terms of rT? Remember to check whether the torque is positive (results in CCW motion) or negative (results in CW motion). A rope of tension 1T applies a force at radius 4R on the spool. It is located at 12 o'clock and…
Please refer to the picture with the formulas and constants that need to be used in this problem. Harzan wants to swing from one bank of the river to the other using an overhaning vine. As he swings, he traces out an arc of a circle. Part 1) Please draw and label a free body diagram of Harzan at the bottom of the swing. Answer: we have to discuss the motion of the swinging person Part 2) What forces act as the radial force in the circular motion? Answer: In the radial direction centrifugal force will act as a source of tension Part 3) Is this uniform circular motion? Explain Answer: The motion is similar to that of a pendulum, thus the vine-swinger system acts like a physical pendulum, the motion will not be uniform circular. Part 4) The vine is 6.2 m long, and Harzan's mass is 85 kg. At the bottom of his swing, he is travelling at 4.3 m/s. What is the magnitide of the radial acceleration that Harzan experiences? Part 5) How much tension must the vine support in order to safely…
