Question

A car travels 90meters due north in 15 seconds.Then the car turns around and travels 40 meters due south . what is the magnitude and direction of the car's resultant displacement?​

Answer 1

Answer:

Algebraically an average velocity is defined as,

=

where, d is the displacement and t is the time taken for that displacement.

When you calculate the displacement of the car, the net displacement is

= 90 − 40 = 50 ℎ.

Therefore, the average velocity is

=

50

20 = 2.5 m/s
