A.) How long does it take from the moment when the motorcycle starts to accelerate until it catches up with the car? In other words, find [tex](t1-t2)[/tex]. Express the time numerically in seconds.

B.) What is the initial speed of the car? Express the speed numerically in meters per second. answer must be in m/s

C.) How far did the motorcycle travel from the moment when it starts to accelerate (at time t1 ) until it catches up with the car (at time t2)? Answer numerically in meters.

ok what i really get stuck on is what formula should i use? i really dont know how to start problems like this, because it's im always like "What formula should i use?" can someone help me start this question and tell me your secret on how you know what formula you use on any physics problem? i like physics and i think it's awesome how it works, but it's so hard for me.
