Question

An object falling from the building having mass 30 kg and the height of the building is 25m calculate work done​

Answer 1

• mass=m=30kg
• Height=h=25m
• Acceleration due to gravity=g=10m/s^2

We have to find potential energy

$\boxed{\sf E_p=mgh}$

$\\ \sf\longmapsto E_p=(25)(10)(30)$

$\\ \sf\longmapsto E_p=250(30)$

$\\ \sf\longmapsto E_p=7500J$

Answer 2

Answer:

mass=m=30kg

Height=h=25m

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

We have to find potential energy

Ep = mgh

→ Ep = (25) (10) (30)

→ Ep = 250 (30)

Ep = = 7500J
