1. 1/2 points1 Previous Answers My Notes Ask Your Te A plane lands on a runway with a speed of 110 m/s, moving east, and it slows to a stop in 11.0 s. What is the magnitude and direction of the plane's average acceleration during this time interval? HINT: You might let East be the positive direction and West be the negative direction in your calculations. The sign of your answer will indicate the direction. magnitude (NOTE: magnitudes are ALWAYS positive) m/s direction due west Save 2 0-12 points KnightCPWA3 2.P.007

Explanation / Answer

Velocity changes from +110m/s to 0m/s in 11 seconds
v = u + at

a = (v - u)/t

a = ((0-110)/11

a = -10 m/s2 (negative means the direction of the acceleration is opposite to the initial velocity)

Magnitude = 10 m/s2

Direction = due west
