O The table lamp in the figure below has a circular base ofdiameter 120 mm and a height of 300 mm. It stands on arough horizontal surface. The centre of mass of the tablelamp is 60 mm above its base.300 mmcentreof mass60 mm120 mm8 Na) With the help of a diagram, explain why the tablelamp topples when a certain angle of tilt is exceeded.Find the value of this angle.b) Explain why it is possible for the centre of mass to beonly 60 mm above the base and not midway betweenthe top and base of the lamp.c) When a horizontal force of 8 N is applied at the topof the table lamp as shown in the lower diagram,the table lamp just begins to pivot about its base.Calculate the weight of the table lamp.d) Give TWO reasons why fitting a thin but heavy metaldisc of diameter 160 mm to the base of the lampwould improve its stability.11 By giving THREE examples, one for each, of bodies in

Suppose a horse leans against a wall as shown in the figure. The total of the horse and rider is 500 kg. Part a : calculate the magnitude of the force in newtons on each foot of the horse in the figure assuming the center of the mass of the horse between and the weight is equally divided between the two feet on the ground. Part b: what is the minimum coefficient of friction between the hooves and ground? Note that the force exerted by the wall is horizontal.
You are on a pirate ship and being forced to walk the plank (Figure 1). You are standing at the point marked C. The plank is nailed onto the deck at point A, and rests on the support 0.75 m away from A. The center of mass of the uniform plank is located at point B. Your mass is 85 kg and the mass of the plank is 45 kg. Part A What is the minimum downward force the nails must exert on the plank to hold it in place? Express your answer to two significant figures and include the appropriate units. |Fnails|= for Part A for Part Vndo for Part redo for Part A ret for Part A keyboard shortcuts Value Units

A person is pushing a fully loaded 25.40 kg wheelbarrow at constant velocity along a plank that makes an angle a = 32.0° with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its length L. What is the magnitude of the total force F, the person must apply so that the wheelbarrow is parallel to that plank? You may neglect the radius of the wheel in your analysis. The F. gravitational acceleration is g = 9.81 m/s². F = N
You have a summer internship at NASA and are working on plans for a new space station to be launched into orbit around the Earth. The design of the space station is shown. i It is to be constructed in the shape of a hollow ring of mass 52,000 kg. The structures other than the ring shown in the figure have negligible mass compared to the ring. Members of the crew will walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 140 m. The thickness of the ring is very small compared to the radius, so we can model the ring as a hoop. At rest when constructed, the ring is to be set rotating about its axis so that the people standing inside on this deck experience an effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. Your supervisor asks you to determine the following: (a) the time interval during which the rockets must be fired if each…
