Answer:
No work was done.
W = 0
Explanation:
Work is said to be done whenever a force of one newton moves a body of one kilogram through a distance of one meter. Meaning the applied force has to move the body from a point of rest through certain distance.
Work = force × distance
So, in the case of this question, we only have the force been applied, but no distance was covered. Hence, no work was done.
W = 3000× 0 meter
W = 0
Answer:
83.055 m
Explanation:
According to the given scenario, the calculation of skid distance is shown below:-

Where
u = 11.3
v = 0
t = 14.7
Now placing these values to the above formula,
So,

= 83.055 m
Therefore for computing the skid distance we simply applied the above formula i.e by considering the all items given in the question
Aperture is measured in F-stops, in which the f-stops is the amount of light allowed to pass through the aperture, which simply put means that the smaller the aperture, the higher the f-stops. What it does is reduce the amount of light that reaches the film, so the higher the f-stops, the less light reaches the film.
