SUMMARY
The discussion centers on calculating the kinetic energy required to accelerate a car from 10-20 m/s versus 20-30 m/s using the formula KE = 1/2mv². The calculations show that the change in kinetic energy for the first interval (10-20 m/s) is 150 joules, while for the second interval (20-30 m/s), it is 250 joules. Thus, accelerating from 20-30 m/s requires an additional 100 joules of energy compared to the first interval. This conclusion is based on the principle of conservation of energy.
