Situation B: Two vehicles of the same mass moving at different speed. 10 m/s
1.500 kg
The kinetic
TETRY
of
travelling at 10 m/s is four times
the kinetic energy
Of
Car
travelling at 5 ms/s.
Why is this so?
Car travelling at 10 m/s has twice
as much the speed of the other
car. Since the mass is the same
for both
vehicles, using the
formula of kinetic energy.
a mv2
5 m/s
KE
1500 kg
= m(2v)
= m (4v2)
Therefore, KE 4(mv). The
kinetic energy is increased four
times.
