## Homework Statement

1. How much distance does a car cover during this period: from 60 Km/Hr, a car comes to a dead stop in 10 seconds, from the time the brake is applied (answer in m/s)

2. What will be the braking distance if the car travels at 90Km/hour (answer in m/s)

## Homework Equations

s = ut + 1/2at^2

v^2 = u^2 + 2as

## The Attempt at a Solution

NOTE: What equation is best used for the first question, is it distance=v*t OR one of the complicated distance equations since acceleration needs to be found. I am unsure whether you must retain 60 km/hr as initial velocity to 90 km/hr as final velocity in the 2nd question.
