How to Calculate and Solve for Mass, Velocity and Kinetic Energy | The Calculator Encyclopedia

To calculate 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]
That is, 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 are 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}
That is, 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 are 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}
Then, v = √¹²⁰ / ₅
v = √24
v = 4.89

Therefore, the velocity is 4.89.
