An automobile having a mass of 1100 kg initially moves along a level highway at 120 km/h relative to the highway. It then climbs
soldier1979 [14.2K]

Answer:

-6111.11\ \text{kJ}

863.28\ \text{kJ}

Explanation:

m = Mass of automobile = 1100 kg

v = Velocity of car = 120 km/h = \dfrac{120}{3.6}\ \text{m/s}

h = Height of hill = 80 m

g = Acceleration due to gravity = 9.81\ \text{m/s}^2

Change in kinetic energy

KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}

Change in kinetic energy is -6111.11\ \text{kJ}

Change in potential energy is given by

PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}

The change in potential energy is 863.28\ \text{kJ}.
