Question

Calculate the kinetic energy of a moving ball at the velocity of 10ms and mass 50kg

Answer 1

Given:

• Mass = 50kg
• Velocity = 10m/s

To Find:

• Kinetic energy = ?

Solution:

Formula to be used:

${\qquad}\sf \: k = \frac{1}{2} \times m {v}^{2}$

Now putting the value

$\sf \implies \: \frac{1}{2} \times 50 \times {10}^{2} \\ \\ \sf \implies\: \frac{1}{2} \times 50 \times 10 \times 10 \\ \\ \sf \implies \: 2500J$

Hence, Kinetic energy is 2500J.
