Question

The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is J.

Answer 1

Hello!

We have the following data:

KE (Kinetic Energy) = ? (in Joule)
m (mass) = 0.5 Kg
v (speed) = 10 m/s

Formula to calculate kinetic energy:

$KE = \frac{1}{2} *m*v^2$

Solving:

$KE = \frac{1}{2} *m*v^2$

$KE = \frac{1}{2} *0.5*10^2$

$KE = \frac{1}{2} *0.5*100$

$KE = \frac{50}{2}$

$\boxed{\boxed{KE = 25\:Joule}}\Longleftarrow(kinetic\:energy\:of\:a\:ball)\end{array}}\qquad\quad\checkmark$


I hope this helps! =)

Answer 2

Answer:

KE (Kinetic Energy) = ? (in Joule)

m (mass) = 0.5 Kg

v (speed) = 10 m/s
