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)

1.	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)
Answer» Solution :`2T = MG + mv^(2)//L, V = SQRT((2T-mg)l//m)`, FORCE = 2T
