Question

A car is driving down the highway at a 50 m/s. Suddenly, the driver sees an accident and slams on his breaks, coming to a complete stop in 10 seconds. How far did the car travel before coming to a stop?

Answer 1

Given parameters:

Speed of the car = 50m/s

Time  = 10s

Unknown:

Distance traveled before the car stopped = ?

We need to establish speed - time - distance relationship.

Speed is the rate of change of distance with time. It is a scalar quantity .

Mathematically;

            Speed  = $\frac{distance}{time}$

    Distance  = speed x time

Input the parameters and solve;

    Distance  = 50 x 10  = 500m

The car traveled 500m before it stopped.
