Heya Friend ☺
Thanks for asking
Here simple calculation Applying kinetic energy formula and getting the value like this
Given M1=20 kgs
M2= 5 kgs
force required =4 N
Use
kinetic energy formula and put the velocity as time reference
1:2
hope it helps you ☺

ck233:
how you find velocity
force is required
yeah you're right
if borce exet on body than it acire accerlation which is velocity /time
yeah dude i know
i couldn't understand her language where she had written 4
kg witf
sry wt means weight and it was if
