Question

13 m ahead of his car. he applies the brakes and the car decelerates at a uniform rate of 8.0 m/s^2. if the driver's reaction time is .25 seconds, will the car stop before hitting the child?

Explain.

also, assuming the reaction time to be .50 seconds for teh driver, will the car stop before hitting the child?

Answer 1

well 8.0 m/s^2 means a deceleration of 8 meters per second, every second.

you need to convert 40km/h in meters per second and work ot out from there

  

Answer 2
