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? (The equation is Acceleration (a) = Final velocity (vf) - Initial velocity (Vi) divided by time (t)

a=-76.5

well. you're pretty much given all values  there
initial velocity is 153 when the plane lands
needs to get to 0, to final velocitiy will be 0

when it starts off is 0seconds
and needs to do it in 2.0seconds

I assume the accelartion will be the rate of change between those two points, and thus their slope
