A motorist traveling at a constant velocity of 20 m/s passes a school-crossing corner where the speed limit is 10 m/s (about 22 mi/h). A police officer on a motorcycle stopped at the corner starts off in pursuit with a constant acceleration of 2.5 m/s^2. What is the officer's speed when she catches up with the car? What is the total distance of the officer has traveled at that point?
set their two position functions equal to each other the function for the motorist is r=20t the function for the police car is r=(2.5/2)t^2 I assumed they started at the same time so 20t = (2.5/2)t^2 solve for t and then plug into the velocity function for police car and the position function of the police car
Does this make sense to you?
what position equation would you use to derive the function? my teacher is picky
