Question

I GIVE MEDALS.
While competing in the Olympics, an athlete hurls a discus with a velocity of 14 m/s at an angle of 51. What is the horizontal component of the discus's velocity?

A. 7.1 m/s
B. 10.9 m/s
C. 12.2 m/s
D. 8.8 m/s

Answer 1

Use a right triangle, where the initial velocity is the hypotenuse and the angle given is the angle between the hypotenuse and x-component. Use trig.

Answer 2

u = 14 cos (51)

Answer 3

Nicely done.
