A 1000 kg boulder sits at the top of a 50-meter high cliff. Determine the amount of potential energy possessed by the boulder if the acceleration due to gravity is 9.8 m/s2. The boulder has_______(magnitude/ number)_______(units) of Potential Energy.

Answers

Answer 1

Answer:

490000J

Explanation:

Given parameters:

Mass of boulder  = 1000kg

Height of cliff = 50m

Acceleration due to gravity  = 9.8m/s²

Unknown:

Potential energy  = ?

Solution:

Potential energy is due to the position of a body. It is expressed as;

        P.E  = mgH

m is the mass

g is the acceleration due gravity

H is the height

  Now insert the parameters and solve;

            P.E  = 1000 x 9.8 x 50  = 490000J

Answer 2

Data:  

m = 1000 kg

h = 50 m

g = 9.8 m/s^2

Find:  

P.E = ?

Formula:  

P.E = mgh

Solution:  

P.E = mgh

P.E = (1000)*(9.8)*(50)

P.E = 490000 J

Result:

P.E = 490000 Joule
