Question

Calculate the potential energy of a 1.5 kg hammer that is located at a height of 2 m

Answer 1

Answer: 29.43 Joules

Step-by-step explanation:

PE=mgh

PE=potential energy

M=1.5kg

G=9.81m/s^2

H=2m

PE=29.43J

Answer 2

`\boxed {\boxed {\sf 29.4 \ J}}`

Step-by-step explanation:

Potential energy is the energy an object possesses due to its position. It is calculated using the following formula:

`PE=mgh`

The mass of the hammer is 1.5 kilograms and its height is 2 meters. Assuming this is on Earth, the acceleration due to gravity is 9.8 meters per second squared.

• m= 1.5 kg
• g= 9.8 m/s²
• h= 2 m

Substitute these values into the formula.

`PE= (1.5 \ kg)(9.8 \ m/s^2)(2 \ m)`

Multiply the numbers together.

`PE=(14.7 \ kg *m/s^2)(2 \ m)`

`PE=29.4 \ kg*m^2/s^2`

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. Our answer of 29.4 kg*m²/s² is equal to 29.4 J.

`PE= 29.4 \ J`

The potential energy of the hammer is 29.4 Joules.
