Answer:
980 kg m²/s²
Explanation:
m= 18*9.8 (9.8 is the value of gravity)
k.e. = 1/2mv² = (1/2)* 18*9.8 * {12*( 5/18)}² =980 kg m²/s²

Answer:
hii mate here is the answer to your question:-
given---- mass (m) = 18kg.
speed or velocity ( in case of a straight line)
=12km/hr.
as we are aware of the fact that K.E = 1/2mv^2
therefore, kinetic energy = 1/2×18×12^2
=9×144=1267 joule.
