A 40kg child sits on a swing supported by two chains,each 3 m long. If the tension in each chain at lowest point in 350 N, then the child's speed at the lowest point is [Take g=10`m//s^2`]

A boy of mass m sits in a swing supported by two chains, each of length l . At the lowest point the tension in each chain is T. What is (i) the boy's speed at the lowest point and (ii) the force of the seat on the boy at the lowest point. (Assume that the seat has no mass)

In the above problem, the force exerted by the pilot on the seat at the lowest point of the circle will be [Take g=10 m//s^2 ]

In the above problem, the force exerted by the pilot on the seat at the lowest point of the circle will be [Take g=10 m//s^2 ]

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 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 stone of mass 0.3g is tied to one end of string 0.8m long and rotated in a vertical circle At what speed of the stone will the tension in the string be zero at the highest point of the circle ? What will be the tesion at the lowest point in this case ? Take g = 980 cm^(-2) .

Tension in the rope at the rigid support is (g=10m//s^(2))

Tension in the rope at the rigid support is (g=10m//s^(2))

A chain of mass 'm' is attached at two points A and B of two fixed walls as shown in the Find the tension in the chain near the walls at point A and at the mid point C .
