Answer:The net force acting on the car is 3×103 Newtons
Explanation:
Answer:
the acceleration during the collision is: - 5
Explanation:
Using the formula:
![a=\frac{\Delta\,v}{\Delta\,t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%5CDelta%5C%2Cv%7D%7B%5CDelta%5C%2Ct%7D)
we get:
![a=\frac{-0.4-0.6}{0.2} \,\frac{m}{s^2} =\frac{-1}{0.2} \,\frac{m}{s^2} =-5\,\,\frac{m}{s^2}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B-0.4-0.6%7D%7B0.2%7D%20%5C%2C%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%3D%5Cfrac%7B-1%7D%7B0.2%7D%20%5C%2C%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%3D-5%5C%2C%5C%2C%5Cfrac%7Bm%7D%7Bs%5E2%7D)
Answer:Newton's three laws of motion relate to each other in that they lay a foundation for the principles of things in motion, then build upon that foundation. For example, the first law of motion,...

Answer:
None.
Explanation:
The weight of the astronaut is equal to the force of gravity the astronaut feels that depends on the mass of the planet.
Because the mass of the Earth is different than that of Jupiter, Saturn and Mars, the astronaut's weight will change when he/she travels to either planets.
