Answer: 600 m

Explanation:

Speed V is defined as the distance traveled d in a especific time t:  

V=\frac{d}{t}  

Where:  

V=343 m/s \approx 300 m/s is the speed of sound  

t=2 s the time you hear the thunder after you see the flash of lightning  

We need to find the distance at which you are from the lightning strike:  

300 m/s=\frac{d}{2 s}  

Finding d:  

d=(300 m/s)(2 s)  

Finally:  

d=600 m

Prove that acceleration due to gravity is independent to the mass of falling object.<br>​
iren2701 [21]

Answer:

The value of acceleration due to gravity is independent of mass of the body.

Explanation:

Let us consider the mass of the object as m and mass of earth as M

Therefore, force between the object and earth would be given by: F = GMm/d²

This force is equal to the weight of the object, i.e. mg

Thus;

mg = GMm/d²

g = GM/d²

Therefore, the value of acceleration due to gravity is independent of mass of the body.

A rock is thrown from a height of 2.0 m at a window that is located 9.0 m above the ground. The initial velocity of the rock is
ELEN [110]

Answer:

The value is  x = 11.81 \ m

Explanation:

From the question we are told that

   The height is h =  2.0 m

   The height of the window is d = 9.0 \ m

    The initial velocity of the rock is u =  20 \ m/s

    The angle at which it is thrown is \theta  =  40

Generally the  vertical component of the velocity of the stone is mathematically represented as

    v_y = 20 sin (40)

=>v_y = 12.86 \ m/s

Generally the height of the window from the ground is mathematically represented as using kinematic equation as

      d = h  +  v_yt + \frac{1}{2} gt^2

=>   9 = 2  +12.86 t + \frac{1}{2} * - 9.8 t^2

Here g is negative -9.8 m/s^2 because the direction of the stone is against gravity

   So

       4.9 t^2 -12.86 t + 7 =0

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

       v_x =  20 * cos(40 )

=>    v_x =  15.32 \  m/s

Generally the distance between the person throwing the rock and the window is mathematically represented as

       x =  v_x * t

=>    x =  15.32 * 0.771

=>    x = 11.81 \ m
