Question

A $110 k g$ panda is riding on a $3.0 m$ long swing whose mass can be considered negligible. The highest point of its arc occurs when the swing makes a $20^{o}$ angle with the vertical.
What is the magnitude of the total tension in the ropes of the swing at that point?

Solution

The correct option is C $1013 N$
Given : $m = 110$ kg
Tension in the string $T = m g$ $c o s 20^{o} = 110 \times 9.8 \times 0.94 = 1013$ N
