Amotor vehicle has a mass of 1200 kg, and is traveling at a velocity of 70 km/hours to the southeast. as it travels over a hill, it leaves the pavement and reaches a maximum height of 3 meters off the pavement. calculate the vehicle's gravitational energy. *

35280 J of Gravitational energy

Solution:

Given:

Mass of the vehicle,(m)=1200kg

Maximum height reached,(h)= 3 m

Gravitational energy or gravitational potential energy can be calculated as;

Gravitational Energy = 35280 J

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
