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:
[tex]KE = \frac{1}{2} *m*v^2[/tex]
Solving:
[tex]KE = \frac{1}{2} *m*v^2[/tex]
[tex]KE = \frac{1}{2} *0.5*10^2[/tex]
[tex]KE = \frac{1}{2} *0.5*100[/tex]
[tex]KE = \frac{50}{2} [/tex]
[tex]\boxed{\boxed{KE = 25\:Joule}}\Longleftarrow(kinetic\:energy\:of\:a\:ball)\end{array}}\qquad\quad\checkmark[/tex]
I hope this helps! =)
