Two students are observing the motion of a Mercedes Benz. They calculate, with various handy dandy gadgets, that the Benz is changing its speed constantly by 2.2 m/s every second while moving along a straight road.
Student 1: The Benz is traveling at a constant velocity. Therefore at the end of 2 seconds it's speed will still be 2.2 m/s.
Student 2: No, the Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.
Which student do you agree with and why? Discuss all parts of all statements made by both students. Saying I agree with student 1 or 2 or neither will not suffice.

Student 2 is correct. The Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.

Final velocity of the Benz

The final velocity of the benz is determined by using first kinematic equation;

v = u + at

where;

  • u is the initial velocity
  • a is the final velocity = (2.2 m/s) / 1s = 2.2 m/s²
  • t is the time

v = 2.2 + (2.2 x 2)

v = 6.6 m/s

Change in velocity

Δv = 6.6 m/s - 2.2 m/s = 4.4 m/s

Thus, student 2 is correct. The Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.
