Question

A roller coaster is at the top of a 102 m hill and a mass of 120 kg. The coaster (at this

Answer 1

• Height=h=102m
• Mass=m=120g
• Acceleration due to gravity=g=10m/s^2

$\\ \sf\longmapsto P.E=mgh$

• P E means potential energy

$\\ \sf\longmapsto P.E=102(120)(10)$

$\\ \sf\longmapsto P.E=122400J$
