Answer:

198.20 N

Explanation:

Given that,

Mass of a heavy bag, m = 25 kg

The bag is attached to the ceiling until it makes an angle of 36 degrees to the vertical.

We need to find the force must the boxer exert on the bag. The force acting on the bag is given by :

[tex]F=mg\cos\theta\\\\=25\times 9.8\times \cos(36)\\\\=198.20\ N[/tex]

So, the required force is 198.20 N.
