Answer:
The planes average acceleration in magnitude and direction = 8.846 m/s² moving east
Explanation:
Acceleration: This can be defined as the rate of change of velocity. The S.I Unit of acceleration is m/s². Acceleration is a vector quantity because it can be represented both in magnitude and in direction.
Acceleration can be represented mathematically as
a = v/t.................................... Equation 1
Where a = acceleration, v = velocity, t= time.
Given: v = 115 m/s, t = 13.0 s
Substituting these values into equation 1
a = 115/13
a = 8.846 m/s² moving east
Thus the planes average acceleration in magnitude and direction = 8.846 m/s² moving east
