A fighter jet lands on the flight deck of an aircraft carrier that has a length of 300.0 m. The jet must reduce its speed from about 153 km/h to exactly 0 km/h in 2.0 s. What is the jet’s acceleration?

a = -153/2 = -76.5 km/hr/s

But you probably want that in m/s, so
(-153km/hr * 1hr/3600s * 100m/km)/2.0s = -21.25 m/s

Well, if the jet needs to go from 153 km/h to a complete stop in just 2.0 seconds, it's safe to say that it's practicing for the "Jet Olympics" in the category of "Emergency Stoppage." The length of the aircraft carrier is 300.0 m, and in those 2.0 seconds, the jet has to decelerate to 0 km/h. So, to find the acceleration, we can use the equation:

acceleration = (final velocity - initial velocity) / time

First, let's convert the velocities from km/h to m/s. We have an initial velocity of 153 km/h, which is about 42.5 m/s. The final velocity is 0 km/h, so that's easy peasy, it's 0 m/s. The time is 2.0 seconds.

Now, plug those values into the equation:

acceleration = (0 m/s - 42.5 m/s) / 2.0 s

Now, let's do a little bit of math to find the result:

acceleration = -42.5 m/s / 2.0 s

acceleration = -21.25 m/s²

So, the jet's acceleration is -21.25 m/s². And remember, the negative sign indicates that the jet is decelerating or slowing down. And boy, it better slow down fast if it wants to avoid becoming a UFO (Unidentified Floating Object) on that aircraft carrier!

To find the jet's acceleration, we can use the formula:

acceleration = (final velocity - initial velocity) / time

Given that the final velocity (vf) of the jet is 0 km/h, the initial velocity (vi) is 153 km/h, and the time (t) is 2.0 s, we can substitute these values into the formula:

acceleration = (0 km/h - 153 km/h) / 2.0 s

Let's convert the velocities from km/h to m/s since the time is given in seconds:

1 km/h = 0.2778 m/s

Substituting the velocities into the formula, we have:

acceleration = (0 m/s - 42.5 m/s) / 2.0 s

Simplifying the expression, we get:

acceleration = -42.5 m/s / 2.0 s

Calculating the value, we find:

acceleration = -21.25 m/s²

Therefore, the jet's acceleration is -21.25 m/s². The negative sign indicates that the acceleration is in the opposite direction to its initial motion, which means the jet is decelerating.

To determine the jet's acceleration, we can use the following formula:

acceleration = (final velocity - initial velocity) / time

Given:
Initial velocity (u) = 153 km/h = 42.5 m/s (since 1 km/h = 1/3.6 m/s)
Final velocity (v) = 0 km/h = 0 m/s
Time (t) = 2.0 s

Substituting the given values into the formula, we have:

acceleration = (0 m/s - 42.5 m/s) / 2.0 s
acceleration = -42.5 m/s / 2.0 s
acceleration = -21.25 m/s²

Therefore, the jet's acceleration is approximately -21.25 m/s². The negative sign indicates that the acceleration is in the opposite direction of the initial velocity.
