If vx = 3 meters/second and vy = 4 meters/second, what is the magnitude of the resultant velocity?

Answer

5m/s

Explanation:

Resultant is defined as the single velocity/forces that balances all other velocities/forces acting on a body. It is also defined as the vector sum of the vectors acting on a body.

Given two vectors in the x and y direction i.e Vx = 3m/s Vy = 4m/s

The formula of the resultant of both vectors will be;

R²= Vx² + Vy²

Where R is the resultant vector

R²= 3²+4²

R²=9+16

R²=25

R=√25

R=5m/s

Therefore, the magnitude of the resultant velocity is 5m/s
