Question

2. Your car is travelling at constant speed of 100 km/h when an emergency situati pr To better understand the role that reaction time plays in slowing your car, the follo motkA diagram shows the motion of your car and the distance d your car travels after you see the emergency situation (th) and your car begins to slow down (t) Average t, is o.la direction of motion Estimate the distance, in meters, the car travels during your reaction time in braking. Hint Use the relationship connecting distance traveled, average speed and time. IOo 8 Reaction Time Laboratory 2

Explanation / Answer

from the given data,
speed of the car, v = 100 km/hr

= 100*1000 m/(60*60 s)

= 27.78 m/s

distance travelled, d = v*reaction time

= 27.78*reaction time

= .......... m

reaction time is not given in the question.

substitute reaction time in the above equation and get d.
