Another Two Dimensional motion question

In summary: Try cosine.cos35 = x/17than would you use the final speed formulasquare root Vx^2+Vy^2In summary, the second baseman throws the ball to the first baseman at a speed of 17.0 m/s and an angle of 35.0° above the horizontal. Using trigonometry, the horizontal and vertical components of the ball's initial velocity can be found. To find the horizontal component, use cosine with the angle of 35.0° and the initial speed of 17.0 m/s. The vertical component can be found using sine with the same angle and speed. The horizontal component remains constant throughout the throw, while the vertical component changes as the ball reaches the peak of its arc

No. Vx= 3.6 m/s. You need to find Vy before you can find Vfinal.

oh, than to find Vy = Voy - at?
 
  • #38
Yep.

than what is the time and Voy
i know that a = -9.8

Vo is the initial velocity, you have the initial speed [17.0 m/s] and the angle [35.0° above the horizontal] and a hint:

the sine helps you solve for the vertical component.
