Answer:
10
Explanation:
As we know from work energy theorem that work done by external force is change in kinetic energy
So from all above we can say
W = k_f - K_i
in order to find work done we can say
W = F.d
here we have
F = 5 N
d = 2 m
so we have
W = (5)(2) J
W = 10 J
so we will have so from above equation we can say that final kinetic energy will be same as work done
K = 10 J
