Find Acceleration and velocity of vault or car(from rest). This is info from the movie Fast 5(Vault Heist).
time = 15s
Vault ≈ 74,750 lb ≈ 33,903.03 kg
Car ≈ 1900 kg
Money in vault ≈ 4,900 kg
Estimate coefficient (tires & concrete) ≈ 1
Estimate coefficient (steel & vault) ≈ 0.57
I have not a clue what the problem is. What is the relationship of the vault to the car?

The cars (2 cars) are pulling a vault out of the wall of a police station. What is the acceleration and velocity from rest? This question comes from the vault heist scene in the movie Fast 5.
Now the issue is what is net force: Net force=pulling force-friction
friction is easy to figure (m*mu*g)
so exactly what is the pulling force? Not given. Not known.
