Answer:
The initial velocity of the motorcycle is 18.29 m/s.
Explanation:
Given that,
When a motorcycle hits the brakes, its final speed becomes zero.
Acceleration of the motorcycle, 
Time taken to stop, t = 2.85 s
We need to find the initial velocity of the motorcycle. The first equation of kinematics is given by :
So, the initial velocity of the motorcycle is 18.29 m/s.
1. the conductivity of the material
2. temprature differences
3.thickness of the material
4. area of the material
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>
