Fup = m (9.81 + v^2/R)
2*265 = 30 (9.81+v^2/1.4)
(b) 2*265 up assuming the seat has no mass :)
A 30 kg child sits in a swing supported by two chains, each 1.4 m long.
(a) If the tension in each chain at the lowest point is 265 N, find the child’s speed at the lowest point. (Neglect the mass of the seat.)
Answer in units of m/s.
(b) Find the force of the seat on the child at the lowest point.
