Answer:
The value is
Explanation:
From the question we are told that
The height is h = 2.0 m
The height of the window is
The initial velocity of the rock is
The angle at which it is thrown is
Generally the vertical component of the velocity of the stone is mathematically represented as
=>
Generally the height of the window from the ground is mathematically represented as using kinematic equation as
=>
Here g is negative -9.8 m/s^2 because the direction of the stone is against gravity
So
Solving this quadratic equation using quadratic formula we obtain
t = 0.770 s
Generally the velocity of the stone on the x axis is mathematically represented as
=>
Generally the distance between the person throwing the rock and the window is mathematically represented as
=>
=>
I answered this question the answer is about 4039200
Anything that can be dissolved/mixed into a solvent. Sugar, salt, acetic acid, etc
Vf = 0 m/s
<span>t = 10 s </span>
<span>a = ? </span>
<span>a = Vf - Vi /t </span>
<span>a = -2m/s^2 </span>
<span>"a" is decelration
i hope this helps :)</span>
