Answer:
The velocity is
Explanation:
From the question we are told that
The time taken by the ball is t = 2.5 seconds
The angle made with the horizontal is
Generally the vertical component of the initial velocity is mathematically represented as
Generally at maximum height of the ball the velocity is v = 0 m/s and the time take to reach this maximum height is
=> [This because t is duration for the to a fro travel of the ball]
Generally from kinematic equation
Here given that the direction is against gravity
=>
=>
=>
<span>The amplitude of the sound wave (the difference between it's maxima and minima, essentially) determines the strenth, or loudness, of the sound wave. </span>
Answer:the will have the same acceleration
Explanation:according to fállelos theory they land at the same time
Using the kinematic equation d = V_0 * t + 1/2 * a * t^2, where d is height you can rewrite this to be d = 1/2*g*t^2 or 4.9t^2
g = a because this is a free fall
d = 1/2 * 9.81m/s^2 * 2.5^2
d = 30.65625m
d = 30.7m
Answer: I think the last one, I am not sure but from what I learned what it looks like.
