Final answer:
The force necessary to produce the given deceleration is 411,600 N.
Step-by-step explanation:
The force necessary to produce a deceleration can be found using Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. In this case, the deceleration is given as 196 m/s² and the mass of the system is 2100 kg.
To find the force, we can use the formula: force = mass * acceleration. Plugging in the given values, we get: force = 2100 kg * 196 m/s².
Simplifying this calculation, we find that the force necessary to produce the given deceleration is 411,600 N.
