Answer 1

Answer:

48 j

Explanation:

w = 60x0.8 = 48j

Answer 2

The work done by the folk lift is 470.4 J.

Explanation:

Given that,

Mass of bag =20 kg

Number of bag = 3

Distance = 80 cm

We need to calculate the work done

Using formula of work done

$W=F\cdot d$

$W=mg\cdot d$

m = mass of bag

d = displacement

Put the value into the formula

$W=(20\times3)\times9.8\times80\times10^{-2}$

$W=470.4\ J$

Hence, The work done by the folk lift is 470.4 J.
