Answer:30.2m
Step-by-step explanation:
Let
be the displacement of Susan.
Let
be the initial velocity of Susan.
Let
be the acceleration of Susan.
Let
be the time taken by Susan.
Given that Susan starts from rest.
From the given information we can assume that no additional forces are acting on the sled.So,the acceleration is constant.
As we know from the equations of motion,

Given that,

So,
