sally and lisa have identical compact cars sally drives on the freeway with a great speed than lisa. which car has more kinetic energy
greater speed, same mass, more KE.
KE= 1/2 m v^2
To determine which car, Sally's or Lisa's, has more kinetic energy, we need to consider two factors: the mass of the car and the speed at which it is traveling.
The formula for calculating kinetic energy is:
Kinetic energy = 1/2 * mass * velocity^2
Given that Sally drives at a greater speed than Lisa, we can conclude that Sally's car has more kinetic energy if the mass of both cars is the same.
However, if the mass of the cars is different, we need more information about their masses to make a definitive statement.
