C)1 ton
D)1 metric ton

Question

Quizplus · Accepted Answer

First, we need to convert the acceleration from kmph/s to m/s^2. 
9 kmph/s = 2.5 m/s^2 
Then, we can use the formula: 
Force = mass x acceleration 
Force = 1000 kg x 2.5 m/s^2 = 2500 N 
Therefore, the force required to accelerate 1000 kg of mass at a rate of 9 kmph/s is 2500 N, which is choice B.
