Given K.E. = 5J
Velocity = 5 ms^-1
We have to calculate mass here
K.E. = mv^2/2
5 = m (5)^2
m = 0.4 Kg
This is the answer
Velocity = 5 ms^-1
We have to calculate mass here
K.E. = mv^2/2
5 = m (5)^2
m = 0.4 Kg
This is the answer

sorry this answer is wrong
no man, but according to the values you gave , it must be correct as kinetic energy =1|/2 mv*v
