Answer 1

Answer:

kya pata ........................

Answer 2

Answer:

Explanation:

Step 1: Enumerate the given values.

Given:

m = 5 kg

h = 3 m

g = 9.8 m/s²

Step 2: Identify what is being asked.

Required:

Potential Energy

Step 3: Solve for Potential Energy

Solution:

The formula for Potential Energy is given by:

PE = mgh

where: PE - Potential Energy

m - mass

g - gravitational acceleration constant

h - height of object from the reference level

Substituting the value of m,g and h in the formula,

PE = (5 kg)(9.8 m/s²)(3 m)

PE = 147 kgm²/s² or 147 Nm or 147 J
