Answer:
8.6 m/s
Explanation:
The components of the initial velocity of the ball can be found by using the equations:
[tex]v_x = v cos \theta\\v_y = v sin \theta[/tex]
where
[tex]v_x[/tex] is the horizontal component
[tex]v_y[/tex] is the vertical component
v is the magnitude of the velocity
[tex]\theta[/tex] is the angle above the horizontal
Substituting:
v = 15 m/s
[tex]\theta=35^{\circ}[/tex]
We find:
[tex]v_x = (15)(cos 35^{\circ})=12.3 m/s\\v_y = (15)(sin 35^{\circ})=8.6 m/s[/tex]
