Question

How much gravitational potential energy is lost when a rock of mass 3, point, 0, k, g,3.0kg falls to the foot of a 250, m,250m cliff on the Moon where 'g,g' is 1, point, 6, N, slash, k, g,1.6N/kg?

Answer 1

E = 1200 J

Step-by-step explanation:

Data:

m = 3 kg

h = 250 m

g = 1,6 H/kg

Find:

E - ?

-----------------------------------

Solution:

E = mgh

Calculations:

E = 3 kg · 250 m · 1,6 H/kg = 1200 J

Answer: E = 1200 J.
