The image above represents kinetic energy.

To compute for the kinetic energy, two essential parameters are needed and these parameters are **mass (m) **and **velocity (v).**

The formula for calculating the kinetic energy:

K.E. = 0.5mv²

Where;

K.E. = Kinetic Energy

m = Mass

v = Velocity

Let’s solve an example;

Find the kinetic energy when the mass is 6 and the velocity is 18.

This implies that;

m = Mass = 6

v = Velocity = 18

K.E. = 0.5mv²

K.E. = 0.5[6 x 18²]

K.E. = 0.5[6 x 324]

K.E. = 0.5[1944]

K.E. = 972

Therefore, the **kinetic energy** is **972 Joules (J).**

**Calculating the Mass when Kinetic Energy and Velocity is Given.**

m = ^{K.E} / _{0.5v2}

Where;

m = Mass

K.E. = Kinetic Energy

v = Velocity

Let’s solve an example;

Find the mass when the kinetic energy is 320 and a velocity of 20.

This implies that;

K.E. = Kinetic Energy = 320

v = Velocity = 20

m = ^{K.E} / _{0.5v2}

m = ^{320} / _{0.5 x 202}

m = ^{320} / _{0.5 x 40}

m = ^{320} / _{20}

m = 16

Therefore, the **mass** is **16 kg.**

**Calculating the Velocity when Kinetic Energy and Mass is Given.**

v = √^{K.E} / _{0.5m}

Where;

v = Velocity

m = Mass

K.E. = Kinetic Energy

Let’s solve an example;

Find the velocity when the kinetic energy is 120 and a of mass 10.

This implies that;

m = Mass = 10

K.E. = Kinetic Energy = 120

v = √^{K.E} / _{0.5m}

v = √^{120} / _{0.5 x 10}

v = √^{120} / _{5}

v = √24

v = 4.89

Therefore, the **velocity** is **4.89**.
