Question

While competing in the Olympics, an athlete hurls a discus with a velocity of 31 m/s at an angle of 41. What is the vertical component of the discus's velocity?

Answer 1

20.3 m/s I know it cause i was on apex looking for the answer because im stupid and got it wrong then it gave me the right answer

Answer 2

Answer:

vertical component of velocity is given as

$v_y = 31 sin41 = 20.34 m/s$

Explanation:

As we know that if a vector of a given magnitude is inclined at some angle with horizontal then its components with horizontal and vertical is given as

$A_x = Acos\theta$

$A_y = Asin\theta$

here vector is given as

$v = 31 m/s$

angle is given as

$\theta = 41^0$

now the vertical component is

$v_y = 31sin41 = 20.34 m/s$
