Question

a velocity of 20m/s has its x-component 12m/s. What is its y-components? Find the angel at which the velocity is inclined with the x-axis?​

Answer 1

Explanation:

the resultant velocity is given by the formula v=\sqrt{ x^{2} + y^{2} }

x

2

+y

2

so, 10m/s=\sqrt{ x^{2} + (5 \sqrt{2} )^{2} }

x

2

+(5

2

)

2

squaring on both sides, 100=x²+50

thus, x²=50

x=5√2

hope it helps....
