An aircraft, traveling northward, lands on a runway with a speed of 77 m/s. once it touches down, it slows to 6.3 m/s over 705 m of runway. what is the average acceleration (magnitude and direction) of the plane during landing (in m/s2)

magnitude

Direction

Opposite to the velocity of aircraft

Explanation:

As we know that the initial speed of the aircraft when it land on the ground is

now the final speed of the aircraft when it covers 705 m on runway is given as

so here we know that

so now we can say that

c) up is the direction the magnetic force is acting on the charge.
