3) A jet airplane makes a landing traveling due south. Its speed when it touches the ground is 69.45 m/s, and it takes 13.05 seconds to stop. What are the magnitude and direction of the plane\'s acceleration?

Solution

Intial velocity=69.45m/s

Final velocity = 0 m/s

Time taken to stop = 13.05seconds

v=u+at

0=69.45+13.05a

a=-5.32 m/s²

The magnitude of acceleration is negative because the plane is decelerating.

Therefore, the magnitude of acceeration is 5.32m/s²

The direction is due North
