Answer:
1.43 s
Explanation:
The time it takes for the container to reach the ground is determined only by the vertical motion of the container, which is a free-fall motion, so a uniformly accelerated motion with a constant acceleration of g=9.8 m/s^2 towards the ground.
The vertical distance covered by an object in free fall is given by
where
u = 0 is the initial vertical speed
t is the time
a= g = 9.8 m/s^2 is the acceleration
since u=0, it can be rewritten as
And substituting S=10.0 m, we can solve for t, to find the duration of the fall:
Answer:
14.9 m /s
Explanation:
n = n° x v /[ v -v (s) ]
n is apparent frequency , n° is source frequency,v is speed of sound and v(s)
speed of source.
2300 = 2200 x 343 / [343 -v(s)]
v (s ) = 14.9 m /s.
