The equation of GPE is mgH, where m is mass, g is gravitational acceleration, and H is the height.
If we're solving for the change in GPE, then:
∆
= mg∆H
<u>Input our given values for m and g:</u>
∆
= 0.25 * 9.80 * ∆H
<u>The book falls from 2 meters high to 0.5 meters high, so:</u>
∆
= 0.25 * 9.80 * (2.0 - 0.5)
∆
= 0.25 * 9.80 * 1.5
∆
= 3.675 (J)
<u>Adjust for significant figures:</u>
∆
= 3.7 (J)
The change in gravitational potential energy was 3.7 (J)

Answer:
91.3 kg
Explanation:
weight = m*g
m: mass
g: gravity = 9.8 or 10 (depends on what your instructor tells you to use)
mass = w/g
895/9.8 = 91.3 KG
