Mass=57.1 Kg

Distance 69.5 m

G= 9.8

Theta= 34.9

So I'm trying to find the amount of work done on mass.

2. Relevant equations

F=ma

Work=Fcos(theta)D

3. The attempt at a solution

Okay so i started out finding Force by newtons 2nd law.

F=ma

f=57.1(9.8)

F=559.58

Okay so then I went with force to the work fomula.

Work=559.58cos(34.9)69.5

and that gave me 31896.37

but this answer proved to be incorrect?
