Two cars emerge side by side from a tunnel. Car A is traveling with a speed of 60 km/h and has an acceleration of 40 km/h/min. Car B has a speed of 40 km/h and an acceleration of 60 km/h/min. Which car is passing the other as they come out of the tunnel? Explain.

Car A is passing Car B, however a few moments later Car B will pass Car A.

Duh, you just SAID they are side by side leaving the tunnelđź™‚

A speeding motorist travels past a stationary police officer at a speed of 120km/hr. The officer immediately begins pursuit at a constant acceleration of 10km/hr/s.

a. How long will it take for the police officer to reach the speeder, assuming the speeder maintains a constant speed?

b. How fast will the officer be traveling at that time?

Regardless of their accelerations the current fastest car will pull ahead.
