Answer:
Explanation:
Given
Motorcyclist speed=12 m/s
maximum acceleration
distance=39 m
Let x be the distance traveled by motorist in his reaction time
therefore remaining 39-x will be traveled with acceleration
s=39-x
v=0
u=12 m/s
x=27 m
Therefore he traveled 27 m in his reaction time
t=2.25 s
(b)If his reaction time is 2.56 sec
then distance traveled in his reaction time
Remaining distance 39-30.72=8.28 m
therefore its velocity when it reaches the deer
v=6.681 m/s
