Respuesta :

Chelboy

Answer:

Explanation:

Mass(m)=310g=0.31kg

Distance(h)=1.5m

Acceleration due to gravity (g)=10m/s^2

Work=m x g x h

Work=0.31 x 10 x 1.5

Work=4.65joules

The minimum work done by heart will be "4.65 Joules".

Given values:

  • Mass, m = 310 g or, 0.31 kg
  • Distance, h = 1.5 m
  • Acceleration, g = 10 m/s²

As we know,

→ [tex]Work \ done = mgh[/tex]

By putting the values, we get

                     [tex]= 0.31\times 10\times 1.5[/tex]

                     [tex]= 4.65 \ J[/tex]
