The direction of the magnetic force is to the right.
<h3>What is the magnetic field?</h3>
The magnetic field is the region in space where the influence of the magnet is felt. The magnetic force is always in the direction of the magnetic field.

Answer:
18.15m/s
Explanation:
Recall for coefficient of kinetic friction
F=UR
We're F=m*a= U*m*g
Hence a= U*g
We're a= acceleration,U coefficient of kinetic friction,g= acceleration due to gravity hence a=24*0.7=6.867m/s^2 because break was applied it is a negative acceleration hence a= -6.867m/s^2
But V=v+at at final velocity V=0
Hence 6.867*T=v T=v/6.867
But average speed =v/2
Using Newton law of motion
S=(V+v)T/2
Substitute for S,V,v and T
24=(v/2)v/6.867
v^2=329.6
V=18.15m/s
