Answer:
B.) 4,500
Explanation:
The formula for force is force is equal to Mass (M) multiplied by Acceleration (A)
F (N) = M (Mass) × A (Acceleration)
In the question, the Mass is 1,200 kg and the Acceleration is 45 m/s^2 (meters per second squared).
Substitute the Mass (1,200) and the Acceleration (45) in the formula for force (F (N) = M (Mass) × A (Acceleration)
F = 1,200 × 45
F = 54,000
Divide by 12 because in the problem it says 12 seconds.
F = 54,000 ÷ 12
F = 4,500
The force required is 4,500N
Sorry if there's something missing and if there are mistakes. I'm not really sure if my explanation is entirely correct, but I got the answer in the end. Again I'm truly sorry. I hope it helps.
