A 550 kg dragster accelerates from rest to a final speed of 110 m/s in 400 m (about a quarter of a mile) and encounters an average frictional force of 1200 N. What is its average power output in watts and horsepower if this takes 7.30 s
Answers: 2
are initial and final kinetic energy of the system.
= initial velocity of the system
=final velocity of the system
= friction force
