Question

A wagon loaded with iron blocks is pushed up an inclined plane to its highest point. The total mass of the wagon is 50 kg and the height of the topmost point from the ground is 5 meters. What is the total potential energy of the wagon at the top?​

Answer 1

To Find :-

• The total potential energy of the wagon at the top.

Solution :-

• Mass (m) = 50 kg
• Height (h) = 5 m
• Acceleration due to gravity (g) = 10 m/s²

The formula for potential energy is given below.

$\red\bigstar$ P.E = mgh

Where,

• P.E is the potential energy of the object in Joules.

• m is the mass of the object in kg.

• g is the acceleration due to gravity in m/s².

• h is the height of the object with respect to the reference point in m.

[ Put the values ]

$\longrightarrow$ P.E = 50 × 10 × 5

$\longrightarrow$ P.E = 50 × 50

$\longrightarrow$ P.E = 2500 joule $\green\bigstar$

Therefore,

The total potential energy of the wagon at the top is 2500 J.

Answer 2

Explanation:

Given:-

mass (m)=50kg

Height=h=5m

Acceleration due to gravity =g=${10m/s}^{2}$

To find:-

potential energy

Solution:-

as we know that

${:}\longrightarrow$${\boxed {P.E=mgh}}$

${:}\longrightarrow$50×10×5

${:}\longrightarrow$50×50

${:}\longrightarrow$2500Joule

${:}\longrightarrow$${\underline{\boxed{\bf {P.E=2500J}}}}$
