1. The problem statement, all variables and given/known data A motorbike is driving at a constant velocity of 25m/s, and 80 meters in front of it, a car is accelerating from standing still, with a constant acceleration of 3m/s2. When will the bike overtake the car? 2. Relevant equations s=vt Possibly s=ut+0.5at2 3. The attempt at a solution I've found that the bike reaches the car's starting point after 3.2s, at which point the car is now 15.36m ahead and has a velocity of 9.6m/s. I don't know how to proceed from here other than to keep calculating how long it takes for the bike to get to the point the car is in, and repeat until they are at the same spot. Surely there must be a more practical way.
