An arrow is fired vertically upwards by a bow and reaches an altitude of 134 m. Find the initial speed of the arrow on the ground level.

Explanation:

Let the initial speed be u . final speed = 0

v² = u² - 2gh

v is final speed , u is initial speed , h is height .

0 = u² - 2g x 134

u² = 2 x 9.8 x 134

u = 51.25 m /s .

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
