A pilot claims to have seen a UFO moving initially at a speed of about 440 m/s in an easterly direction and then, in a time interval of only 1.0 s, turning 45 degrees and moving southeast at 440 m/s. Compute the UFO’s average acceleration during the turn.
eastward acceleration, ae = (440 m/s - 440 m/s * cos45) / 1sec
= 128.87 m/s^2
southward acceleration, as = 440m/s * sin45 / 1sec
= 311.13 m/s^2
total acceleration a = = sqrt(ae2 +
as2)
= sqrt(128.872 + 311.13 2)
= 336.76 m/s^2
