Question

PLEASE HELP ASAP!!!
What is the horizontal velocity of the ball?
​

Answer 1

`5*√(3) =8.660 (m)/(s)`

Step-by-step explanation:

The horizontal component of he velocity is found using the trigonometric definition of "cosine" of an angle in a right angle triangle:

`cos(\theta)=(adj)/(hyp) \\cos(30)=(x)/(10) \\10*cos(30)=x\\10* (√(3) )/(2) =x\\x=5*√(3) =8.660 (m)/(s)`
