To find the average acceleration of the boat, we need to convert the units of speed from km/h to m/s and use the formula for acceleration.
Given:
Initial speed (u) = 0 km/h
Final speed (v) = unknown
Time (t) = 10.0 s
To convert km/h to m/s, we use the conversion factor:
1 km/h = 1000 m/3600 s = 0.2778 m/s
So, the final speed (v) can be calculated by:
v = (0.2778 m/s) × (final speed in km/h)
Now, let's calculate the final speed:
v = (0.2778 m/s) × 0 km/h
v = 0 m/s
The formula for average acceleration (a) is:
a = (v - u) / t
Substituting the known values:
a = (0 m/s - 0 m/s) / 10.0 s
a = 0 m/s / 10.0 s
a = 0 m/s^2
Therefore, the average acceleration of the boat is 0 meters per second squared (m/s^2).
