A baby stroller is a rest on top of a hill which is 10 m high. The stroller and baby have a mass of 20 kg. What is the potential energy of the baby and stroller?

Respuesta :

potential energy = mass x gravity x height
= 20 x 9.81 x 10
= 1962J

Answer: 1960 Joules

Explanation: Potential energy is the energy possessed by an object by virtue of its position.

[tex]P.E=m\times g\times h[/tex]

P.E = potential energy

m = mass of body = 20 kg

g = acceleration due to gravity =[tex]9.8ms^{-2}[/tex]

h = height of body = 10 m

[tex]P.E=20kg\times 9.8ms^{-2}\times 10m=1960kgm^2s^{-2}=1960Joules[/tex]

[tex](1kgm^2s^{-2}=1Joule)[/tex]
