Answer:

Explanation:
Given data
Distance S=6.10 m
Initial Speed u=12.0 m/s
To find
Final Speed v
Solution
From third equation of motion we know that:

where
v is final velocity
u is initial velocity
a is acceleration
S is distance
Substitute the given values to find v

Answer:
2.4525 N
Explanation:
The earths gravity is 9.81 N/Kg
And so to work this out you would multiply 9.81 by 0.250 which equals to 2.4525N
The only thing in either one of those formulas that we don't know is the mass of the book.
