Weight of a body is 100N, it's weight on the moon is

We know

So

Weight of body on earth is 100N

And we know that the weight of a body on moon is 1/6 of weight on earth. Thus the weight on moon will be

Thus, The weight of body on moon will be 16.6 Newton...~

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

overcharge is the right answer system
