Answer:
C. 500 J
Explanation:The equation of Kinetic energy is KE = (mv^2)/2 therefore here m, which is mass, is 10 and v, which is velocity, is 10 as well. So KE = (10x10^2)/2 = 1000/2 = 500. And there we get the answer as 500 hence the answer is C. 500J
If u don’t understand this, leave a comment below. (Hope u understood!)
Kinetic energy = (1/2) (m) (v^2)
The question tells us (m) and (v) .
KE = (1/2) (10kg) (10 m/s)^2
KE = (5 kg) (100 m^2/s^2)
KE = 500 N-m
KE = 500 Joules
