<span>This is basically a division equation. Solve the top and the bottom, then divide. The numerator (top part) is 3.95 multiplied by 10 to the second power, which is the same as 3.95 times 100, which is the same as 395.
The denominator is 1.5 times 10 to the 6th power, which is the same as 1.5 multiplied by 1,000,000, which is the same as 1,500,000.
Dividing 395 by 1,500,000 we get 0.0002633333, or 2.633333e-4, which is another way of putting it.</span>
The speed of the sport car at the time of impact is 6.61 m/s.
<h3>What is the frictional force of the two cars?</h3>
Frictional force of the two cars = coefficient of kinetic frictin × mass × acceleration of gravity
= 0.8 × (2500+940) × 9.8
= 26970N
<h3>What is the acceleration of the skidded cars?</h3>
- As per Newton's second law of motion, force = mass × acceleration
- Acceleration= force / mass
= 26,970/3440
= 7.8 m/s²
<h3>What is the velocity of the sport car at the time of impact?</h3>
- As per Newton's equation of motion, V² - U² = 2aS
- Here, V = 0 m/s, a= -7.8 m/s², S= 2.8 m
- So, 0²-U²= 2×(-7.8)×2.8
=> U = √43.68
= 6.61 m/s
Thus, we can conclude that the speed of the sport car at the time of impact is 6.61 m/s.

Answer:
Explanation:
We need to assume that the density of the concrete is about 2350 Kg/m^3. And using the dimensions of the highway we can calculate the volume of the highway.
I am pretty sure that it is protein for both sausage and chicken because most meats are protein.
