Answer:
100J = K.E
Explanation:
K.E =1/2 *m*v^2
= 1/2*0.500*(20.0)^2
= 1/2 *500/1000 *400
So here 2will cancel with 400,and it will be reduced to 200 then the zeros of 200 will cancel with 1000's zeroes and then when the zeros of 200 get cancelled with the zeroes of 1000 u will be left with 500/10 *2 then cancel 2 with 10 then u get 500/5 then reduce that u get 100.
Hope it helps pls mark as brainliest!!!
