Final answer:
The given statement 'The same rocket sled drawn in the figure is decelerated at a rate of 199 m/s²' is true. To calculate the force needed to decelerate a rocket sled at 196 m/s² with a mass of 2100 kg, apply Newton's second law, leading to a required force of 411,600 Newtons. So, the correct answer is a) True.
Step-by-step explanation:
The student's question concerns calculating the necessary force to decelerate a rocket sled, which is a physics problem typically encountered in high school.
To determine the force needed to produce a deceleration of 196 m/s² for a rocket sled with a mass of 2100 kg, one can use Newton's second law, which states that force equals mass times acceleration (F = ma).
The calculation is as follows:
Force (F) = mass (m) × deceleration (a)
Therefore, F = 2100 kg × 196 m/s²
F = 411,600 N
Thus, a force of 411,600 Newtons is required to decelerate the rocket sled at the rate of 196 m/s² with the rockets off.
Thus, the correct answer is a) True.
