A motor 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

tatuchka [14]

Answer: 35280 J of Gravitational energy

Solution:

Given:

Mass of the vehicle,(m)=1200kg

$\text{acceleration due to gravity} (g)=9.8 m/s^2$

Maximum height reached,(h)= 3 m

Gravitational energy or gravitational potential energy can be calculated as;

$\text{gravitational energy}=mgh$

$\text{gravitational energy}=(1200 Kg)(9.8 m/s^2)(3 m)=35280 J$

Gravitational Energy = 35280 J
