Question

An object of mass 5kg falls from a height of 5m above the ground. Find the loss of potential energy of the mass

Answer 1

Answer:

loss in pottential energy = 245 joule

Step by step explanations:

Given,

An object of mass 5kg falls from a height of 5m above the ground

mass of object = 5 kg

height from which it is dropped = 5 m

to find

the loss of potential energy of the mass

so,

loss in pottential energy = potential energy at its maximum height

pottential energy = Mgh

here,

M = mass of the object

= 5 kg

g = gravitational acceleration

= 9.8 m/s²

h = height of ground from the object

= 5 m

so,

pottential energy = 5 × 9.8 × 5

= 245 joule

so,

loss in pottential energy = 245 joule
