An automobile manufacturer claims that its product will, starting from rest, travel 400 m in 9.0 s. What is the acceleration required to do this?

Acceleration, a = 9.877m/s²

Explanation:

Given the following data;

Distance, d = 400m

Time, t = 9secs

Since it's starting from rest, initial velocity, u = 0

To solve for acceleration, we would use the second equation of motion;

Substituting into the values into the equation;

Cross multiplying, we have;

a = 9.877m/s²

Therefore, the automobile would have to accelerate at a constant rate of 9.877m/s²

their mass and volume are dep

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
