Explanation:
Work = change in energy
W = ΔKE
W = ½ m (v² − v₀²)
W = ½ (1750 kg) ((27 m/s)² − (15 m/s)²)
W = 441,000 J
W = 441 kJ

Answer:
The force exerted is 6189.4 N
Solution:
As per the question:
Area of the book, A =
Mass of the book, m = 3 kg
Pressure of the book, P =
Now,
Pressure, P =
Force, F = PA =
Force on mass of 3 kg, F' = mg =
Now, the force at the bottom is given by:
F'' = F + F' = 6160 + 29.4 = 6189.4 N
