angle with horizontal it hits the ground?

(a) 55° (b) 45° (c) 60° (d) 75°
​

Answer 1

Answer:

the Correct answer is b)45°

Step-by-step explanation:

hope you get it and mark me as brilliant and thank me:-):-)!!

Answer 2

Given:-

t = 10 sec

g = 10 m/s^2

To find :-

θ= ?

Solution:-

AS we know that

v = u + at

therfore:-

Uy - direcation = 0

= v = gt = 100m/s

therefore:-

Ux of object = velocity = 100m/s

tanθ = 100/100 = 1

thata = 45
