1 A child weighing 220 N is swinging back and forth on a ropeattached to a tree branch. The
rope is 3.8 m long and has negligible mass.
a) At the lowest point of the swing, the child is moving with speed4.2 m/s. What is the tension
in the rope at this instant?
b) What is the direction and magnitude of the childâs accelerationat the highest point of the
swing when the rope makes an angle ? with the vertical?
c) What is the tension in the rope at the highest point of theswing?
