Question

Holden is trying to turn man the velocity of his car, he went 20 meters east, turned around and left 40 meters less, he turned the car one more time, and when 35 meters east, his car was 15 metres from the starting line. This took 5 seconds, what is the car
velocity

Answer 1

Answer:

3 m/s east

Explanation:

The velocity of the car is given by:

$v=\frac{d}{t}$

where

d is the displacement

t is the time taken

The displacement of the car does not depend on the path of the car, but just on it the difference between its final position and its starting position, so it is equal to 15 metres east. The time taken is 5 seconds, therefore the velocity is equal to

$v=\frac{15 m}{5 s}=3 m/s$

and the direction is east.
