Question

A velocity of 10m/s has it y components 5underroot 2m/s calculate its x component

Answer 1

Answer:

Resultant Velocity = 10 m/s

X component = ? , Y component  = 5√2 m/s

We know that,

Resultant² =  ( x component )² + ( y component )²

Let the x component be denoted as 'x'

=> 10² = x² + ( 5√2 )²

=> 100 = x² + ( 25 × 2 )

=> 100 = x² + 50

=> x² = 100 - 50

=> x² = 50

=> x = √50 = √ 25 × 2 = 5√2 m/s

Hence the x - component is also 5√2 m/s.
