While competing in the Olympics, an athlete hurls a discus with a velocity of 15 m/s at an angle of 20. What is the horizontal component of the discus's velocity?

Respuesta :

To find this simply draw a triangle with the hypotenuse being 15 and the angle between the hypotenuse and bottom leg is 20. The horizontal component is the horizontal leg. to find this you would use cos and then solve for the bottom leg.

When you do, you get 15cos(20)

Answer: 14.1

Explanation: 15cos(20) = 14.1
