Is there a way to calculate the acceleration (in g's) applied to a truck as it is stopped in a runaway escape ramp? Do I need to know how long it takes or how far it goes in the ramp to calculate the acceleration?

Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity, meaning it has both magnitude and direction. If an object's acceleration is positive, it is speeding up, and if it is negative, it is slowing down.
Acceleration can be calculated by dividing the change in an object's velocity by the change in time. This is represented by the formula a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
Deceleration is a type of acceleration that occurs when an object's velocity decreases. It is often referred to as negative acceleration and can be caused by forces such as friction or air resistance.
Newton's Second Law of Motion states that acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass. This means that the greater the force applied to an object, the greater its acceleration will be. Similarly, the more massive an object is, the less it will accelerate for a given force.
Yes, acceleration can be negative. This occurs when an object's velocity and acceleration are in opposite directions. For example, if a car is traveling east but slowing down, its acceleration would be in the westward direction, making it negative.
