Respuesta :

Answer:

m = 1.64 kg

Explanation:

Given that,

The work done to lift a body, W = 1,033 J

Height, h = 64 m

We need to find its mass. The work done in lifting the mass is given by :

[tex]W=mgh\\\\m=\dfrac{W}{gh}\\\\m=\dfrac{1033 }{9.8\times 64}\\\\m=1.64\ kg[/tex]

Hence, the mass of the body is 1.64 kg.
