Arock has a mass of 25kg. the acceleration due to gravity is 10m/s2 and the height of the rock is 42m. find the potential energy of the rock. a. 10,500j b. 5,250j c. 220,500j d. 1,050

Option a is correct

Potential Energy of the rock is 10,500j.

Step-by-step explanation:

Given: A rock has a mass (m) of 25 kg, the acceleration due to gravity(g) is and the height of the rock (h) is, 42m.

Formula for potential energy depends on the force acting on the objects is  P=mgh, where P is potential energy, m is mass, g is acceleration due to gravity, and h is height.

Substitute the value of m=25kg , g= and h=42m in above formula; we have,

⇒

Using Conversion:

Therefore, the potential energy of the rock is, P = 10,500j

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
