Question

Example: A stone having a mass of 250 gm is falling from a height. How much kinetic
energy does it have at the moment when its velocity is 2 m/s?​

Answer 1

$\bf\huge\underline{\underline{ Given :- }}$

• a stone of mass 250 g is falling from height

• velocity = 2m/s

$\bf\huge\underline{\underline{ To \: Find:- }}$

• Kinetic Energy

$\bf\huge\underline{\underline{ Answer :- }}$

• mass = 250 g = 0.25 kg

• velocity = 2 m/s

• $\bf Kinetic \: Energy = \frac{1}{2} mv²$

• $\bf Kinetic \: Energy = \frac{1}{2} 0.25 × 2²$

• $\bf\red{Kinetic \: Energy = 0.5 J }$

$\rule{10cm}{0.05cm}$
