  • Force, F = 15 N
  • Mass,m = 3 kg
  • Time taken, t = 5 sec
  • (v-u) =?

<u>As we know </u>–

\qquad\purple{\bf  \twoheadrightarrow  F = m a }

\qquad\bf \twoheadrightarrow  F = m \dfrac{ v-u}{t}

\qquad\sf  \twoheadrightarrow 15 = 3 \times  \dfrac{v-u}{5}

\qquad\sf  \twoheadrightarrow  3 \times  \dfrac{v-u}{5} = 15

\qquad\sf  \twoheadrightarrow  \dfrac{3}{5} \times (v-u) = 15

\qquad\sf  \twoheadrightarrow (v-u)= 15 \times \dfrac{5}{3}

\qquad\sf  \twoheadrightarrow  (v-u)= \cancel{15} \times \dfrac{5}{\cancel{3}}

\qquad\sf  \twoheadrightarrow  v-u = 5 \times 5

\qquad\purple{\bf  \twoheadrightarrow  v-u = 25 }

  • Henceforth, the change in the speed of the body is 25 m/s.

In real life, collisions are neither purely elastic nor inelastic, but instead, fall somewhere between. However, you can still c
Semenov [28]
1. Hitting a baseball is a great example of an elastic collision because there is a complete conservation of kinetic energy; some of the energy of the bat is imparted onto the ball, and the system energy remains the same. Conversely, when a ball is caught in a glove, that is a perfectly inelastic collision: the kinetic energy of the system is completely absorbed into the glove. 
 2. Another example of a completely elastic collision would be someone jumping onto a trampoline: they bounce back up with the same amount of energy with which they began (albeit in the opposite direction).  
3. An example of a perfectly inelastic collision would be someone jumping into a foam pit: the foam absorbs all of the kinetic energy of the jumper and none of it is conserved.

If the labor force of 155 million people is growing by 1.0 percent per year, how many new jobs have to be created each month to
dybincka [34]

First let us compute for the total growth in population.

Growth = 155 million * 0.01

Growth = 1.55 million

 

Since there are 12 months in a year, therefore the new jobs every month should be:

new jobs per month = 1.55 million / 12

<span>new jobs per month = 0.129 million = 129,167 </span>

Elina [12.6K]

Answer:

Alaska: Hydrokinetic Energy Campbell CR9000X used for in-stream hydrokinetic device evaluation. Marine hydrokinetic energy power generation is an emerging sector in the renewable energy portfolio. Hydrokinetic devices convert the energy of waves, tidal currents, ocean currents or river currents into electrical power.
