A flying object is moving at 150 m/s. It makes a complete and final stop in 12 seconds. Calculate the object’s acceleration. pl

12.5m/s^2

Explanation:

Acceleration of an object can be calculated by using the formula;

a = v-u/t

Where; a= acceleration

v= final speed

u= initial speed

t= time

According to this question, the flying object is moving at 150m/s, meaning that ∆V = (v-u) is 150m/s, where initial speed is 0m/s.

Since time is 12s, the acceleration is thus:

a = 150-0/12

a= 150/12

a= 12.5

Hence, the acceleration of the flying object is 12.5m/s^2
