To test a 100 kg electric mobility scooter, engineers drive it up a ramp at a
constant speed of 5.0 m/s. When it passes by the 4.0 m height mark, the
electrical energy stored in the scooter's battery is 80,000 J. Use
g=9.8 m/s².
What is the total mechanical and electrical energy of the electric mobility
scooter at 4.0 m above the ground?
Round your answer to the nearest hundred.
