Answer:
-30 m/s^2
Step-by-step explanation:
The acceleration of the object can be calculated using the formula:
a = (v_f - v_i) / t
where v_i is the initial velocity, v_f is the final velocity, and t is the time taken for the change in velocity.
Given that the object is traveling at an initial velocity of 200 m/s and a final velocity of 50 m/s, and it takes 5 seconds to slow down, we have:
a = (50 m/s - 200 m/s) / 5 s
a = (-150 m/s) / 5 s
a = -30 m/s^2
Therefore, the acceleration of the object is -30 m/s^2. The negative sign indicates that the object is decelerating, or slowing down.
