Hello!
A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?
We have the following data:
m (mass) = 1350 kg
v (velocity) = 12 m/s
KE (kinetic Energy) = ? (in Joule)
Formula to calculate kinetic energy:
\(\boxed{KE = \dfrac{1}{2} *m*v^2}\)
Solving:
\(KE = \dfrac{1}{2} *m*v^2\)
\(KE = \dfrac{1}{2} *1350*12^2\)
\(KE = \dfrac{1}{2} *1350*144\)
\(KE = \dfrac{194400}{2}\)
\(\boxed{\boxed{KE = 97200\:Joule}}\:or\:\boxed{\boxed{KE = 97.2\:kJ}}\Longleftarrow(kinetic\:energy)\:\:\:\:\:\:\bf\blue{\checkmark}\)
