Question

Q. A porter lifta a luggage of 15kg from the ground and puta it on his head 1.5m above the ground. Calculate the work done by jim on the luggage.

PLZZ HELP ME WHO KNOW THE CORRECT ANSWER..........,.!!​

Answer 1

● W = mgh = 15 x 10 x 2 = 300 J

HOPE IT HELPS _________

Answer 2

Given -

• Mass(m) = 15kg

• Height(h) = 1.5m

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

To find -

• Work done by jim.

Solution -

Here, the form of energy is potential energy, so we will take the formula of potential energy, to solve the above question.

Work done = Potential energy (PE)

Now,

Potential energy = mgh

where,

m = mass

g = acceleration due to gravity

h = Height

On substituting the values -

PE = mgh

$\longmapsto$ PE = 15kg × 10m/s × 1.5m

$\longmapsto$ PE = 225 J

$\therefore$ Work done by the Jim is 225 J
