Question

A total of 1,033 J of work is needed to lift a body of unknown mass through a height of 64 m. What is its mass? Round your intermediate step to one decimal place and the final answer to the nearest integer.

Answer 1

m = 1.64 kg

Step-by-step 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 :

`W=mgh\\\\m=(W)/(gh)\\\\m=(1033 )/(9.8* 64)\\\\m=1.64\ kg`

Hence, the mass of the body is 1.64 kg.
