Question

find resultant of two velovities 3m/s onlong east and 4m/s along north
​

Answer 1

Answer:

5m/s

Explanation:

A = (Ax^2 + Ay^2)^0.5

of course you will know the formula resultant is equal to velocity vector is equal to velocity is the square root of of (velocity in x direction)^2 + (Velocity in y direction)^2

Velocity in x direction = Ax = 3m/s

velocity in y direction = Ay = 4m/s

resultant velocity = A = ((3)^2 + (4)^2)^0.5

= (9+16)^0.5

=(25)^0.5

= 5m/s
