Question

An object which has a mass of 70 kg is sitting on a cliff 10m high calculate the objects potential energy. given g=10m/s^2

A.7,000 Joules
B. 3,500 Joules
C. 700 Joules
D. 70 Joules
E. 35 Joules

Answer 1

7,000 joules as MGH is the equation so 70kg * 10 m/s^2 *10m

Answer 2

Answer: Potential Energy = 7,000 Joules(A)

Step-by-step explanation:

Potential Energy is the energy possessed by the virtue of its position and it is given as,

P. E = mgh

Where m is the mass= 70kg

g is acceleration due to gravity =10m/s²

h= height = 10m

P. E = 70×10×10

P. E= 7000J

Therefore the potential energy is 7000J
