Question

Calculate the kinetic energy of a woman of mass 50 kg running at a velocity of 3 m/s.​

Answer 1

Answer:

answer is 225 joules

Explanation:

Using kinetic energy formula

K.E. = 1/2 mv^2

1/2x50x9

25*9

225Joules

Answer 2

Given:

A woman of mass 50 kg runs at a velocity of 3 m/s.

To find:

Kinetic Energy of woman?

Calculation:

• Kinetic Energy is a type of mechanical energy which is present in a moving object by the virtue of its velocity.

• In other words, kinetic energy can be calculated as :

$\rm \: KE = \dfrac{1}{2} \times m \times {v}^{2}$

$\rm \implies \: KE = \dfrac{1}{2} \times 50 \times {3}^{2}$

$\rm \implies \: KE = \dfrac{1}{2} \times 50 \times 9$

$\rm \implies \: KE = 225 \: joule$

So, kinetic energy of woman is 225 Joule.
