Final answer:
To find the magnitude of acceleration of the jet, we can rearrange the equation of motion. Without additional information about the value of t, we cannot calculate the acceleration.
Step-by-step explanation:
To find the magnitude of acceleration of the jet, we can rearrange the equation of motion: final velocity = initial velocity + (acceleration * time). In this case, the final velocity is 71.8 m/s, the initial velocity is 0 m/s (assuming the jet starts from rest), and time is t (unknown). To find the acceleration, we need to know the value of t.
Without additional information about the value of t, we cannot calculate the acceleration.
