Isaac throws an apple straight up from 1.0 m above the ground, reaching a maximum height of 35 meters. Neglecting air resistance

, what is the ball's velocity when it hits the ground?

26.2005 m/s will be the velocity of the apple right when it hits the ground and the initial velocity would be 25.8235 m/s

so Vf=26.2005
and Vi=25.8235

the velocity difference is due to the apple having an initial height of 1 meter

The ball's velocity when it hits the ground is about 26 m/s

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

\large {\boxed {a = \frac{v - u}{t} } }

\large {\boxed {d = \frac{v + u}{2}~t } }

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem !

This problem is about kinematics.

At the maximum height , the velocity of the ball is 0 m/s

<u>Given:</u>

maximum height = h = 35 m

velocity at the maximum height = 0 m/s

gravitational accelerationg = 9.8 m/s²

<u>Unknown:</u>

velocity at the ground = v = ?

<u>Solution:</u>

v^2 = u^2 + 2gh

v^2 = 0^2 + 2(9.8)(35)

v^2 = 686

v = \sqrt {686}

v = 7\sqrt{14} ~ m/s

v \approx 26 ~ m/s

<h3>Conclusion:</h3>

The ball's velocity when it hits the ground is about 26 m/s

How do dog whistles work?
Alchen [17]

<em>The sound it emits comes from what is known as the ultrasonic range, a pitch that is so high humans can't hear it. Dogs can hear these sounds, however, as can cats and other animals. Because of this, the dog whistle is a favored training tool, though it may not be for every dog parent.</em>

Define what is physics​
Lisa [10]

In my own words, I would say that physics is an area of science that seeks to explain and understand the fundamental nature of the dynamics of objects, essentially defining how objects can interact, in space and in time.

natima [27]

Answer:

Nature of Sound Waves Sound is a wave that is created by <u>perturbations</u> and propagated through a <u>medium</u> from one location to another. Type of Wave: <u>longitudinal wave</u><u>.</u> A sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium Sound needs a <u>medium of propagation</u> and a <u>disturbance.</u> Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle.

A child’s toy arrow is launched horizontally from a bow at a speed of 8 m/s from a second story window 4 meters above the ground
Westkost [7]
First find the time it takes to hit the sand t
using s=1/2 g t^2
t^2= 8/9.8= 0.82 seconds
This means the sand was s = 8 * 0.82 = 6.5m away
The horizontal speed stays constant at 8 m/s
The vertical speed =.82 * 9.8 = 8.0 m/s
As the two velocities are equal the angle must be 45 degrees to the horizontal
