Step 1
Given: Mass of the child (m1) = 45 kg Mass of the tire swing (m2) = 3.2 kg Total mass (M) = m1 + m2 Total mass (M) = 45 kg + 3.2 kg Total mass (M) = 48.2 kg Show more…

A 40.0-kg child swings in a swing supported by two chains, each 3.00 m long. The tension in each chain at the lowest point is 350 N. Find (a) the child’s speed at the lowest point and (b) the force exerted by the seat on the child at the lowest point. (Ignore the mass of the seat.)
