Answer 2

Answer:

Hey mate. Here's your answer.

Step-by-step explanation:

Formula for calculating potential energy=mass×gravity×height (mgh).

Given,

Mass= 25g= 0.025kg

Gravity= 10N/kg (assume)

Height= 8m

Potential energy (P.E.)= (0.025×10×8) J

= 2.00J or 2J

2nd way(Taking g=9.8 N/kg)

Given,

Mass= 25g= 0.025kg

Gravity= 9.8 N/kg

Height= 8m

Potential energy (P.E.)= (0.025×9.8×8) J

= 1.96 J
