exercise 4.1 suppose the pilot start agin from rest
To answer this question, we need to understand the concept of acceleration and how it relates to the given scenario. The information provided, "suppose the pilot starts again from rest," implies that the pilot was initially at rest and is starting once more.
Acceleration is the rate at which an object's velocity changes over time. When an object starts from rest, it means that its initial velocity is zero, and any change in velocity will result in acceleration.
In this case, if the pilot starts again from rest, their initial velocity is zero. To calculate the acceleration, we need to know two things: the final velocity and the time it takes to reach that velocity. Unfortunately, the question does not provide these details.
If we assume that the question refers to a specific scenario where the pilot accelerates from rest over a specific time frame, we can use the following formula to calculate the acceleration:
acceleration = change in velocity / time
Since the pilot starts from rest, the change in velocity would be the final velocity. However, without the final velocity or the time, we cannot calculate the acceleration accurately.
To find the answer, you may need to refer to additional information or provide specific details about the final velocity or time frame for acceleration.
