Question

What is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (Formula:)

Answer 1

Answer:

The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J.

Answer 2

The Kinetic Energy is 25J

Given:

Mass - 0.5kg

Velocity - 10m/s

To find:

Kinetic Energy.

Solution:

The formula for kinetic energy is

$E _{k} = \frac{1}{2} m {v}^{2}$

here E(k) is Kinetic energy

m is mass

v is velocity

Mass - 0.5kg

Velocity - 10m/s

adding the given values in the formula

$E _{k} = \frac{1}{2}(0.5)( {10}^{2} )$

$E _{k} = \frac{1}{2} \times \frac{5}{10} \times 100$

$E _{k} = 25J$

Therefore, the Kinetic Energy is 25Joules.
