Answer: 9000 kgm/s
Explanation:
Mass of car = 1500 kg
Speed by which car moves = 6 m/s. Momentum of the car = ?
Recall that:
Linear momentum = Mass x Speed
= 1500kg x 6m/s
= 9000 kgm/s
Thus, the linear momentum of the car is 9000 kgm/s
They expend more oxygen. Littler endotherms lose warmth to the earth proportionately speedier than huge endotherms: less warm mass, protecting layers in littler creatures are less successful by dint of being more slender, and more prominent surface region to volume proportion implies snappier radiation of warmth
Answer:
A larger impulse. A 1-kg ball has twice as much speed as a 10-kg ball.

Answer:
![t=6.96s](https://tex.z-dn.net/?f=t%3D6.96s)
Explanation:
From this exercise, our knowable variables are <u>hight and initial velocity </u>
![v_{oy}=96ft/s](https://tex.z-dn.net/?f=v_%7Boy%7D%3D96ft%2Fs)
![y_{o}=112ft](https://tex.z-dn.net/?f=y_%7Bo%7D%3D112ft)
To find how much time does the <u>ball strike the ground</u>, we need to know that the final position of the ball is y=0ft
![y=y_{o}+v_{oy}t+\frac{1}{2}gt^{2}](https://tex.z-dn.net/?f=y%3Dy_%7Bo%7D%2Bv_%7Boy%7Dt%2B%5Cfrac%7B1%7D%7B2%7Dgt%5E%7B2%7D)
![0=112ft+(96ft/s)t-\frac{1}{2}(32.2ft/s^{2})t^{2}](https://tex.z-dn.net/?f=0%3D112ft%2B%2896ft%2Fs%29t-%5Cfrac%7B1%7D%7B2%7D%2832.2ft%2Fs%5E%7B2%7D%29t%5E%7B2%7D)
Solving for t using quadratic formula
![t=\frac{-b±\sqrt{b^{2}-4ac } }{2a}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B-b%C2%B1%5Csqrt%7Bb%5E%7B2%7D-4ac%20%7D%20%7D%7B2a%7D)
![a=-\frac{1}{2} (32.2)\\b=96\\c=112](https://tex.z-dn.net/?f=a%3D-%5Cfrac%7B1%7D%7B2%7D%20%2832.2%29%5C%5Cb%3D96%5C%5Cc%3D112)
or ![t=6.96s](https://tex.z-dn.net/?f=t%3D6.96s)
<u><em>Since time can't be negative the answer is t=6.96s</em></u>
Answer: The earth is a noisy place. Seismometers, which measure ground movements to detect earthquakes, volcanic eruptions, and manmade explosives, are constantly recording smaller vibrations caused by ocean waves, rushing rivers, and industrial activity.
