Answer:
v = 3.04 m/s
Explanation:
given,
mass of the block, M = 6.6 Kg
horizontal force, F = 12.2 N
distance, L = 2.5 m
initial speed = 0 m/s
speed of the block,v = ?
we now
Work done is equal to change in Kinetic energy.
Work done = Force x displacement
W = Δ K E
Δ K E = Force x displacement
![\dfrac{1}{2}mv^2 - \dfrac{1}{2}mu^2= F .s](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7Dmv%5E2%20-%20%5Cdfrac%7B1%7D%7B2%7Dmu%5E2%3D%20F%20.s)
![\dfrac{1}{2}\times 6.6 \times v^2 - 0= 12.2\times 2.5](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%206.6%20%5Ctimes%20v%5E2%20-%200%3D%2012.2%5Ctimes%202.5)
3.3 v² = 30.5
v² = 9.242
v = 3.04 m/s
speed of the block is equal to 3.04 m/s

Because the Moon has a very small surface area compared to other spacial geo-bodies, it has cooled down much faster than Earth. Any water on the moon would freeze.
