5 m/s2 east
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
2 meter/seconds squared
3 ms-2
The answer will depend on its acceleration.
Average acceleration = (amount of change in speed velocity) / (time for the change) = (30 - 10) / (4) = 5 meters per second2 to the east
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2

The average acceleration can be calculated using the equation of motion: average acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: average acceleration = (26.3 m/s - 0 m/s) / 0.59 s ≈ 44.6 m/s^2.
The idea is that you should: a) Calculate the change in velocity. b) Divide this change by the time. This gives you the average acceleration over the 20 seconds, in this case.
2 meters/second or 7 km/h
