A car traveling at 5.0 m/s speeds up to 10 m/s, with an increase in kinetic energy that requires work W1. Then the car’s speed increases from 10 to 15 m/s, requiring additional work W2. Which of the following relationships accurately compares the two amounts of work:

(a) \(W_{1}>W_{2}\),

(b) \(W_{1}=W_{2}\), or

(c) \(W_{2}>W_{1}\) ?
