Question

A motorcycle has a velocity of 24 m/s, due south as it passes a car with a velocity of 15 m/s due north. What is the magnitude and direction of the velocity of the motorcycle as seen by the driver or car?

A. 39 m/s, southB. 9 m/s, northC. 39 m/s, northD. 15 m/s, south

Answer 1

39 m/s north

Step-by-step explanation:

Let us consider North direction as positive and south as negative

Velocity of motorcycle = -24 m/s

Velocity of car = +15 m/s

The Velocity of the motorcycle as seen by the driver or car

`15-(-24)=39\ m/s`

The speed of the motorcycle as seen by the driver or car is 39 m/s as it is positive the direction is north
