To find the acceleration we must know the initial velocity, final velocity and the total time taken.
As the formula for acceleration is a= v-u/t where v is the final velocity, u is the initial velocity and t is the time taken.
Now we can calculate deceleration. a = (v - u)/t so (50-80)/4 = -7.5 km/s^2. So acceleration comes out to be -7.5 km/s^2.
