Question

Calculate the kinetic energy of a body mass 2 kg moving with a velocity of 0 .1 m/s

Answer 1

Answer:

0.01 J/s

K.E.=1/2×mv^2

Put the values in the formula

=0.01 J/s ans

Answer 2

$\bigstar$ Given

Mass = 2 kg

Velocity = 0.1 m/s

$\bigstar$ To Find

Kinetic Energy

$\bigstar$ Solution

We know that

$\purple{\sf \longrightarrow KE=\dfrac{1}{2}mv^{2}}$

Here

• KE = Kinetic Energy
• m = Mass
• v = Velocity

Units

• KE = Joule (J)
• m = kilogram (kg)
• v = metres per second (m/s)

According to the question

We are asked to find kinetic energy

Therefore

We must find "KE"

Given that

Mass = 2 kg

Velocity = 0.1 m/s

Hence

• m = 2 kg
• v = 0.1 m/s

Substituting the values

We get

$\red{\sf \longrightarrow KE=\dfrac{1}{2} \times 2 \times (0.1)^{2} \ J}$

Therefore

$\pink{\sf \longrightarrow KE=0.01 \ J}$

Hence

$\checkmark$ Kinetic Energy = 0.01 J
