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
<span>impulse =force*time=mass*acceleration*time=mass*... in momentum , I hope this helps you out!! Also have an amazing day and good luck on any further work !!!

A type of material that tries to prevent the flow of thermal energy is called an insulator.
Answer:
Yes. Inertia keeps the speed maintained though my feet leave the ground.
Explanation:
Inertia is the resistance to the change in position of any object this means this resistance will keep me traveling at 30 km/s relative to the sun. If the person wants to change the position we apply force to do that because inertia is opposing us to not do that. We are always traveling with 30km/s relative to sun due to inertia.
