Step 1

Consider the first situation.

Consider the Suzie’s initial velocity be u1, her final velocity be v1, and time taken by her during deceleration be t1.

The given values are,

Step 2

Write the equation of motion, and solve for her acceleration (a1).

Step 3

Consider the second situation.

Consider the Suzie’s initial velocity be u2, her final velocity be v2, and time taken by...
