Question

The object of mass 50kg is moving with the velocity of 2m/s along a straight line. Find out the kinetic energy of the object.​

Answer 1

Explanation:

Heya!!

Here is your answer!!

Given:

m=50 kg.

v=2m/s

K.E =1/2 mv^2

K.E=1/2×50×2×2

K.E.=100 J.

Hope it helps you!!

Answer 2

Answer:

Given :-

• The object of mass 50 kg is moving with the velocity of 2 m/s along a straight line.

To Find :-

• What is the kinetic energy of the object.

Formula Used :-

➦ To find kinetic energy we know that,

${\red{\boxed{\small{\bold{Kinetic\: Energy\: =\: \dfrac{1}{2} m{v}^{2}}}}}}$

Solution :-

Given :

• Mass of an object = 50 kg
• Velocity = 2 m/s

According to the question by using the formula we get,

⇒ $\sf Kinetic\: Energy =\: \dfrac{1}{2} \times 50 \times {(2)}^{2}$

⇒ $\sf Kinetic\: Energy =\: \dfrac{1}{2} \times 50 \times 2 \times 2$

⇒ $\sf Kinetic\: Energy =\: \dfrac{1}{2} \times 50 \times 4$

⇒ $\sf Kinetic\: Energy =\: \dfrac{1}{\cancel{2}} \times {\cancel{200}}$

➠ $\sf\bold{\purple{Kinetic\: Energy =\: 100\: J}}$

${\underline{\boxed{\small{\bf{\therefore The\: kinetic\: energy\: of\: the\: object\: is\: 100\: J\: .}}}}}$
