Question

A baby carriage is sitting at the top of a hill that is 35 m high. The

carriage with the baby has a mass of 1.5 Kg. What is the potential
energy?

Answer 1

P=M(mass)G(Gravity)H(Height)

Gravity=9.8

M=1.5 G=9.8 H=35

so multiply all

=514.5 potential energy

Answer 2

`\boxed {\boxed {\sf E_p= 515.025 \ J}}`

Step-by-step explanation:

Potential energy is found using this formula:

`E_p= mgh`

The mass of the baby in the carriage is 1.5 kilograms and the height is 35 meters. Assuming this is on Earth, the gravitational acceleration is 9.81 meters per square second.

`m=1.5 \ kg \\g= 9.81 \ m/s^2\\h= 35 \ m`

Substitute the values into the formula.

`E_p= (1.5 \ kg )( 9.81 \ m/s^2)(35 \ m )`

Multiply the first numbers together.

`E_p= 14.715 \ kg*m/s^2 (35 \ m )`

Multiply again.

`E_p= 515.025 \ kg*m^2/s^2`

• 1 kilogram square meter per square second is equal to 1 Joule.
• Our answer of 515.025 kg*m²/s² is equal to 515.025 J

`E_p= 515.025 \ J`

The potential energy is 515.025 Joules.
