There are a few ways to go about solving this one. Here's one that takes a few steps, but they're easy to follow. What is the average speed of the car during its rapid deceleration? Assuming constant deceleration, it's (80 - 0)/2 = 40 km/s = 11.1 m/s. (I'm playing fast and loose with the signs at this point.) Divide the stopping distance (50 m) by that speed and you get 4.5 seconds. Acceleration, a, is delta V / delta t = -22.2 / 4.5 = -4.9 m/s2. Since the acceleration of gravity is -9.8 m/s2, the deceleration of the car is about half a g. Note that deceleration is the same as negative acceleration.
Acceleration = 7.09 ms-2 G's = 7.09/9.8 = 0.72
Acceleration is a change in velocity per unit of time. Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this:We have distance/time2, or d/t2Distance is commonly measured in meters, and time in seconds. This makes acceleration appear in meters per second per second, or meters per second squared, or m/sec2.m/s2meters per second squared
9.8 meters per second squared is the acceleration of gravity.
That's unusual. I guess your teacher is trying to make you think a bit. It's a good mental exercise, though. You may recall that the units of acceleration are meters per second squared. That gives you a clue right there. And if you knew Calculus, you'd know that acceleration is the second derivative of distance, s, with respect to time, t: d2s/dt2. So, by now you're probably getting the feeling that the slope of a distance-time squared graph has something to do with acceleration. And you'd be right. Just as the slope of a velocity-time graph is acceleration, the slope of a distance-t2 graph is acceleration. Well, not quite. It's actually ONE HALF the acceleration.
The sprinter's acceleration is 2 meters per second squared.
Acceleration = 7.09 ms-2 G's = 7.09/9.8 = 0.72
Assuming you want the international units: time: second velocity: meters / second distance: meters acceleration: meters / second2
The acceleration of gravity, g, is measured in units of acceleration, which is to say units of distance per time squared. For example, meters per second squared.

Acceleration is typically measured in meters per second squared (m/s^2). This unit represents the change in velocity per unit time.
The acceleration of gravity is approximately 9.81 meters per second squared.
The acceleration due to gravity on Earth is approximately 9.81 meters per second squared.
The acceleration of the object is the rate at which its velocity changes over time, measured in meters per second squared.
The acceleration of gravity is approximately 9.81 meters per second squared.
g is a measurement of acceleration namely 9.8 meters per second squared. When there is an acceleration of 2g then simply multiply 9.8 meters per second squared times 2 or 19.6 meters per second squared.
The rate at which velocity changes is called acceleration. It can be positive (speeding up) or negative (slowing down), and is given in units of distance per time squared (e.g., meters per second squared).
9.8 meters per second squared is the acceleration of gravity.
