Compute all parts of following question:
Question: A motorist traveling with a constant speed of 20m/s passes a school-crossing corner, where the speed limit is 10m/s. Just as the motorist passes, a police officer on a motorcycle at the corner starts off in pursuit with constant acceleration of 2m/s2.
Part A: How much time elapses before the police catches up the motorist?
Part B: What is the officer's speed limit at that point?
Part C: What is the total distance each vehicle has traveled at that point?
Could someone please show me the work and explain how to get the answer.
