Question
A 5,000 Kg monster truck is traveling at 11 m/s. When it sees an obstacle it is going to crush during the Monster truck rally, it speeds up to 18 m/s.
How much has the Kinetic energy of the truck increased during this time?

To calculate the increase in kinetic energy, we can use the formula for kinetic energy:
KE = 0.5 * m * v^2
Where:
KE = Kinetic Energy
m = mass of the monster truck (5000 kg)
v = final velocity - initial velocity (18 m/s - 11 m/s = 7 m/s)
Initial Kinetic Energy:
KE1 = 0.5 * 5000 * (11)^2
KE1 = 0.5 * 5000 * 121
KE1 = 605000 J
Final Kinetic Energy:
KE2 = 0.5 * 5000 * (18)^2
KE2 = 0.5 * 5000 * 324
KE2 = 810000 J
Increase in Kinetic Energy:
ΔKE = KE2 - KE1
ΔKE = 810000 - 605000
ΔKE = 205000 J
Therefore, the increase in kinetic energy during this time is 205,000 Joules.
