You are going 75 km/h along Laurelwood Drive when a police officer jumps out onto the road 42 m ahead of you to wave you down. It takes you 1.15 s to react and apply your brakes. What rate of acceleration must you have in order to stop before hitting the police officer? Is this a reasonable value? [HINT: Friction is limited by the weight of the car] STOP
