Answer:
v = 7.1 m/s
Explanation:
Work applied will change kinetic energy
Fd = ½mv²
v = √(2Fd/m) = √(2(5.0)(10) / 2.0) = √50 = 7.07... m/s

If you meant "What does the Earths system include?" here's your answer. The Earths system includes the atmosphere, which has all the planets air in it.
The linear expansion of iron is a = 1× 10∧ -5 /°C
Length edge is 5cm
Initial surface area of cube A = 6L ∧²
= 150cm∧²
The edge length of cube after being heated from
10°C to 60°C is
L = L[I +a dt] where the dt is = 60-10 = 50°C
5.0025cm
A surface area of the cube after heated is
A' = 6L' ∧²
= 150.1500375 cm∧²
The increased area is = A' -A = 0.15cm∧²
