4) A car is traveling along a straight road at a speed of 50 km/hour. The car stops to pick up some passengers and then resumes its journey at the same speed.

i. What two things affect the kinetic energy of the car as it travels along the road?
ii. What effect will the additional passengers have on the kinetic energy of the car?
iii. Explain why a car traveling at high speed could cause more damage than a car traveling slowly.

Final answer:

Kinetic energy is affected by speed and mass. Additional passengers increase the car's kinetic energy. Driving at high speeds increases damage potential due to the squared relationship between kinetic energy and speed.


Explanation:

Kinetic energy of the car is affected by its speed and mass. The additional passengers will increase the mass of the car, thereby increasing its kinetic energy.

A car traveling at high speed could cause more damage than a car traveling slowly due to the proportionality of kinetic energy to speed squared. This means that the energy and destructive potential of the car increase significantly at higher speeds.
