A body swinging on a swing is 1 metre above the ground at the lowest point. He is 2m above the ground at the highest postiion. What is the velocity at the lowest point of the swing?

In the above question T a is positive at the lowest point for

A pendulum bob can swing along a ciircular path on a smooth inclined plane, as shown in Fig. 3E.31, where m = 1.2 kg, 1 = .075m, theta = 37^(@) . At the lowest point of the circle the tension in the sting is T = 110 N . Determine (a) the speed of the bob at the lowest point, (b) the speed of the bob at the highest point on the circle and (c) the tension in the string at the highest position (a)

A cradle is 'h' meters above the ground at the lowest position and 'H' meters when it is at the highest point. If 'v' is the maximum speed of the swing of total mass 'm' the relation between 'h' and 'H' is

A stone of mass 1kg is tied with a string and it is whirled in a vertical circle of radius 1 m. If tension at the highest point is 14 N, then velocity at lowest point will be

A body is thrown vertically upward from a point A 125 m above the ground. It goes up to a maximum height of 250 m above the ground and passes through A on its downward journey. The velocity of the body when it is at a height of 70 m above the ground is (g=10 m//s^(2))

In the above problem, the force exerted by the seat on the pilot at lowest point is ,

A stone is dropped from a rising balloon at a height of 76 m above the ground and reaches the ground in 6s. What was the velocity of the balloon when the stone was dropped?

A body of mass m is revolving along a vertical circle of radius r such that the sum of its kinetic speed of the body at the highest point is sqrt2 rg then the speed of the body at the lowest point is
