A ball is launched from ground level at 31.8 m/s at an angle of 35° above the horizontal. How far does it go before it is at ground level again?
A) 14 m
B) 21 m
C) 43 m
D) 86 m
E) 97 m

The vertical component of velocity determines how long the ball is in the air. Multiply that by the horizontal component to determine how far it goes before hitting the ground

How do you obtain the vertical and horizontal components? is that the 31.8sin35 and 31.8cos35?

Thanks
