Dr. John Paul Stapp was U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10

Mars2501 [29]

Answer:

a) $a=5.7551 \times g$

b) $d=20.5539\times g$

Explanation:

Given:

speed of rocket initially, $v_i=0\ m.s^{-1}$

top speed of rocket after acceleration, $v=282\ m.s^{-1}$

time taken to get to the top speed, $t_i=5\ m.s^{-1}$

final speed of the rocket, $v_f=0\ m.s^{-1}$

time taken to get to the final speed after reaching the top speed, $t_f=1.4\ s$

Now the acceleration:

$a=\frac{v-v_i}{t_i}$

$a=\frac{282-0}{5}$

$a=56.4\ m.s^{-2}$

Now as a fraction of gravity:

$a=\frac{56.4}{9.8}\times g$

$a=5.7551 \times g$

Now, the deceleration:

$d=\frac{0-282}{1.4}$

$d=201.4285\ m.s^{-2}$

Now as a fraction of gravity:

$d=\frac{201.4285}{9.8}\times g$

$d=20.5539\times g$

In a lab experiment, two identical gliders on an air track are held together by a piece of string, compressing a spring between

ddd [48]

Answer:

Part a)

$v_2 = -0.300$

Part b)

Here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks

Explanation:

Part a)

As we know that there is no external force on the system of two gliders

So here we can use momentum conservation for two gliders

So we will have

$m_1 v_1 + m_2 v_2 = (m_1 + m_2)v_i$

$m_1 = m_2$

$1.300 + v_2 = 2(0.500)$

$v_2 = -0.300$

Part b)

now we will have

initial kinetic energy of both gliders is given as

$K_i = \frac{1}{2}(m + m)(0.500)^2$

$K_i = 0.25m$

Final kinetic energy of two gliders

$K_f = \frac{1}{2}m(0.300)^2 + \frac{1}{2}m(1.300)^2$

$K_f = 0.89 m$

so here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks

i learned that kinetic energy is energy when an object is actually moving not including the moving particles. i also learned tha

GaryK [48]

Answer:

Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.

Explanation:

By moving object creates kinematic energy, that is true. In object itself small particles are moving and creating kinetic energy as well. Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.

Same thing is that when you run or exercise your body temperature is raising(because of moving ).

When you sit your body does not raise temperature.

All of the following processes are the ones that lead directly to the formation of sedimentary rock EXCEPT-

emmasim [6.3K]

Answer:

melting of rock deep underground.

Explanation:

The melting of rocks deep underground does not produce sedimentary rocks. Most igneous rocks are produced by this process.

When molten rocks underground called magma is solidified in the subsurface, it results into the formation of igneous bodies.

Sedimentary rocks forms by the accumulation of sediments.
Inside the basin where the sediments are deposited, they are compacted, cemented and lithified.
Chemical and physical weathering of rocks produces sediments.
