The speed of a car changes from 0 to \( 5 \mathrm{~ms}^{-1} \) in the first phase and from \( 5 \mathrm{~ms}^{-1} \) to \( 10 \mathrm{~ms}^{-1} \) in the second phase and from
P \( 10 \mathrm{~ms}^{-1} \) to \( 15 \mathrm{~ms}^{-1} \) during the third phase. In which phase the increase in kinetic energy is more?
a. First phase
b. Second phase
c. Third phase
d. Same in all the three phases
