Question
A boat has a speed of 2 m/s. It accelerates for half a minute to reach a speed of 8 m/s. Work out the acceleration of the boat.
Answers
GPT 3.5
To calculate the acceleration of the boat, we can use the formula:
acceleration = (final velocity - initial velocity) / time
Given that the boat starts with an initial velocity of 2 m/s and reaches a final velocity of 8 m/s, and the time taken is half a minute, or 30 seconds, we can plug these values into the formula:
acceleration = (8 m/s - 2 m/s) / 30 s
Simplifying,
acceleration = 6 m/s / 30 s
acceleration = 0.2 m/s^2
Therefore, the acceleration of the boat is 0.2 m/s^2.

acceleration = 0.2 m/s^2
Therefore, the acceleration of the boat is 0.2 m/s^2.
