Question

assuming a flat surface with no air resistance, if a projectile is fired at an angle of 30 degrees with an initial velocity of 20 m/s, what will be the distance the object travels before hitting the ground?

Answer 1

20.41m

Step-by-step explanation:

v1=20 m/s

30°

-assuming flat ground and no friction forces acting-

`vf^(2)`
`=vi^(2) +2a`Δx ⇒ Δx
`= vf^(2) -vi^(2) /2a`

`0^(2) -20^(2) /2(-9.8)`

`400/19.6`

`=20.408`⇒
`20.41 m`
