Suzie Lavtaski has reached the end of the ski slope and abruptly decelerates from 20 m/s to 4.56 m/s in 3.49 seconds. Determine Suzie's acceleration rate (in m/s2). (Note: your answer should be negative...) In a similar situation, Suzie Lavtaski abruptly decelerates at the end of a different ski run from 22.6 m/s to 3.73 m/s in 2.89 seconds. Determine the distance she moved (in m) during this braking period.

Step 1

Consider the first situation.

Consider the Suzie’s initial velocity be *u _{1}*, her final velocity be

The given values are,

Step 2

Write the equation of motion, and solve for her acceleration (*a _{1}*).

Step 3

Consider the second situation.

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