Answer:
Original Kinetic Energy= 0 J
Final Kinetic Energy= 7500 J
Total Work Done=7500 J
Explanation:
Kinetic Energy = [tex]\frac{1}{2} m v^{2}[/tex]
where, m= mass of the body/car
v= velocity of the car
Initially car is at rest, so v=0.
Original Kinetic Energy= 0 J
After being accelerated to a velocity of 5m/s Kinetic Energy= [tex]\frac{1}{2} 600[/tex]×[tex]5^{2}[/tex]= 7500 J
Final Kinetic Energy= 7500 J
Total Work Done on the Car = Final Kinetic Energy- Initial Kinetic Energy
This is assuming that the car accelerates under ideal circumstances ie. under no friction or resistance of any kind.
Total Work Done=7500 J
