Which of the following is a reason that a fixed pully makes work easier

A fixed pully is one of many simple machines that can make work easier.  In the fixed pully system we pull down on one side of the rope and the other side goes up.  

Explanation:

The pully can change the direction of force on a rope or belt that moves along its circumference.  

With the same amount of force to pull down as we lift the toy ourselves.  

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

f is prop to m1xm2 double m1 double force
