Q: A racing car has a mass of 1780 kg. The acceleration of gravity is 9.8 m/s^2. What is its kinetic energy if it has a speed of 103 km/h?

A: First note that kinetic energy can be denoted as KE or E_k[\latex]= 728550 J E_k[\latex] = 7.3×10^5 J

Gravity doesn’t affect the kinetic . . . → Read More: Kinetic energy of racing car
