natta225 [31]

Answer:29,930 kJ

Explanation:

Given

Car starts with an initial elevation of 500 m and drives up a hill to reach a final elevation of 2000 m

Final velocity (V)=20 m/s

Energy of car increases by 100 kJ

mass of car(m)=2000 kg

Total Energy =\Delta PE+\Delta KE+\Delta U

\Delta PE=mg(\Delta h)=2000\times 9.81\times (2000-500)

\Delta PE=29,430 kJ

\Delta KE=m\frac{v_2^2-v_1^2}{2}

\Delta KE=2000\times \frac{20^2-0^2}{2}

\Delta KE=400 kJ

\Delta U=100 kJ

Total Energy=29,430+400+100=29,930 kJ
