Ignoring air resistance . . .
After the bomb is released, tangential (horizontal) acceleration is zero,, normal (vertical) acceleration is 9.8 m/s^2 down (gravity).
Answer:
(1) 10^−2 m
Explanation:
The diameter of the tire of an automobile is generally expressed in centimetres; we can say that the diameter of a tire is generally about
d = 20 cm (20 centimetres)
Now we have to verify which option is closest to this value. To do that, we have to keep in mind the equivalence between metres and centimetres; in fact, we have:

This means that we can rewrite the diameter of the tire of a car as

By comparing it with the given options, we see that the closest option is
(1) 10^−2 m
which is therefore the correct answer.
Answer:

Explanation:
The rougher a surface is, the more "holes" are on the edge which means things can get caught on in because multiple holes can catch each other.
