Question

A sumo wrestler is 330 pounds. How much force does the earth exert on him? (Weight)

Answer 1

Answer:

1336.4N

Explanation:

Given parameters:

Mass of the sumo wrestler  = 330pounds

Unknown:

Amount of force the earth exerts on the wrestler  = ?

Solution:

The force the earth exerts on the wrestler is the weight of the man;

  Weight  = mg

where;

 m is the mass

 g is the acceleration due to gravity

   Now,

 let us convert from pounds to kg;

          2.2pounds  = 1kg

         300 pounds  = $\frac{300}{2.2}$   = 136.4kg

Weight  = 136.4kg x 9.8m/s²  = 1336.4N
