A circular pond has a 90 cm wide footpath along the edge. A man walk around the outer edge of the footpath with 66 cm long steps. In 400 steps he makes a full round. What is the radius of the pond.

There is a circular pond and foot-path runs along its boundary. A man walks around it, exactly once, keeping close to the edge. If his step is 66 cm long and he takes exactly 400 steps to go around the pond, what is the diameter of the pond?

A uniform circular board of mass M and radius R is fixed on a horizontal plane and free to rotate along a vertical axis through its center. A man of mass m walks round the edge of the board without slipping, when he has walked completely round the board to his starting point, find the angle turned by the board.

A man of mass 100 kg stands at the rim of a turtable of radius 2 m and moment of inertia 4000 kgm^(2) mounted on a vertical frictionless shaft at its centre. The whole system is initially at rest. The man now walks along the outer edge of the turntable with a velocity of 1m//s relative to the earth a. With what angular velocity and in what direction does the turntable rotate? b. Through what angle will it have rotated when the man reaches his initial position on the turntable? c. Through what angle will it have rotated when the man reaches his initial position relative to the earth?

A ceiling fan has a diameter (of the circle through the outer edges of the three blades) of 120 cm and rpm 1500 at full speed.Consider a particle of mass 1 g sticking at the outer end of a blade. How much force does it experience when the fan runs at full speed? who exerts this force on the particle? How much force does the particle exert on the blade along its surface?

Case Study : Suresh wants to measure the distance of a pond during the visit to his native. He marks points A and B on the opposite edges of the pond as shown in the figure below. To find the distance between the points, he makes a right-angled triangle using rope connecting B with another point C are at a distance of 12 m, connecting C to point D at a distance of 40 m from point C and the connecting D to the point A which is at a distance of 30 m from D such that angle ADC=90^(@) What is the distance AC ?
