Find the kinetic energy of a ball.
<h3><u>Formula</u><u> </u><u>used:-</u><u> </u></h3>
Kinetic energy = 1/2 × m × v²
<h3><u>Solution:-</u><u> </u></h3>
We know that,
Kinetic energy = 1/2 × m × v²
★ Substituting the values in the above formula,we get:
Kinetic energy = 1/2 × 0.5 × 10²
Kinetic energy = 1/2 × 5/10 × 100
kinetic energy = 5/10 × 50
Kinetic energy = 5 × 5
Kinetic energy = 25 Joules
This heavily depends on many other factors and variables that will likely change in your lifetime. Right now, you’re a student, so it’s implausible for you to save large amounts because you most likely don’t earn the same amount of money the average adult does. However, further in your life, you might find that your income has risen significantly, so you can save a larger percentage of your income and keep it for your retirement.
