A roller coaster has 800,000 Joules of kinetic energy and is moving with a speed of 40 m's What is the mass of the roller coaster ing?
As boe in the number for your answer, not the units
The formula for kinetic energy is
The formula for potential energy is
velocidorspeed inms
8 - 10m this really 9.8 m son earth but we will use 10 for simplicity
