Question

A small child weighs 25 kg. If mommy left him sitting on top of the stairs, which are 10 m high, how much energy does the child have?

Answer 1

PE = 2450 Joules

KE = Assuming the child is at rest (not moving or accelerating), there is no Kinetic Energy

Step-by-step explanation:

PE = potential energy

m = mass

g = gravity

h = height

PE = mgh

m = 25 kg

h = 10 m

g = 9.8 (when on Earth, gravity is always this number with more or less decimals)

`PE = (25)(9.8)(10)=2450J`
