A horse runs along a circle with a speed of `20k m//h` . A lantern is at the centre of the circle. A fence is along the tangent to the circle at the point at which the horse starts. Find the speed with which the shadow of the horse moves along the fence at the moment when it covers 1/8 of the circle in km/h.

A man running along a circular track has the speedof 10 km per hour. A source of light is at the centre of the circular track. A wall is along the tangent to the circular track at the point from which he starts.What is the speed of the shadow of the man on the wall when he covers 1/8th of the track? (Assume thetrack to be a line.)

If a point moves along a circle with constant speed, prove that its angular speed about any point on the circle is half of that about the centre.

Find the equation of the circle whose centre is (h, k) and which passes through the point (p, q) .

A point moves along a circle with velocity v = at where a 0.5 m/sec2. Then the total acceleration of the point at the moment when it covered (1/10) th of the circle after beginning of motion -

Assertion : A body is moving along a circle with a constant speed. Its angular momentum about the centre of the circle remains constant Reason : In this situation, a constant non-zero torque acts on the body.

A truck moves along a circular path and describes 100 m when it has traced out 36^(@) at the centre. The radius of the circle is equal to

A body is moving along circle at constant speed Which of the following statement is true?

A point moves along a circle with speed v=at. The total acceleration of the point at a time when it has traced 1//8th of the circumference is:

A particle moves in a circle of radius 4m with a linear speed of 20m//s . Find the angular speed.

A stone tied to the end of a string of length 50 cm is whirled in a horizontal circle with a constant speed . IF the stone makes 40 revolutions in 20 s, then the speed of the stone along the circle is
