Question

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? Formula: PE = m g h (Gravity near earth is 9.8 m/s²)

Answer 1

Potential energy (PE) = mgh

mass of stroller and baby = 20 Kg

PE = 20 Kg x 9.8m/s^2 x 10 m

= 1960 kg m^2/s^2
