4.12 Kinetic Energy

Recall and use the relationship:
KE = Kinetic energy [Joules, J]
m = mass [Kilograms, kg]
v = velocity [metres per second, m/s]

Using the formula…
Calculate the Kinetic Energy of a 10 tonne lorry driving along the expressway at 100km/hr
(NB: 1 tonne = 1000kg; 1km/hr = 0.28m/s)
