Answer:</h2><h3><u>QUESTION①)</u></h3>
<em>✔ First step : calculate the kinetic energy that this car requires to reach 95 km/h</em>
95/ 3,6 ≈ 26,4 m/s
<em>Ec = ½ m x V² </em>
With Ec in J; m in kg; and V in m/s
- Ec = ½ 1750 x 26,4²
- Ec ≈ 610 000 J
<em>✔ Knowing that the car has a p power of 215,000 W, so :
</em>
T = E/P
- T = 610 000/215 000
- T ≈ 2.8 s
<h3>
The car takes 2.8 s to reach 95 km/h </h3>
<h3><u>QUESTION②)</u></h3>
N = 2,8/6,5 x 100 = 43.07
<h3>The car efficiency is 43 % </h3>

Answer:
basaltic cinder cone
Explanation:
The volcano consists of a black ("negro") basaltic cinder cone with associated lava flows, including an aa flow field reaching 4 km to the NE and SW. The frequent eruptions of Cerro Negro have modified its morphology continuously since its birth 160 years ago
Answer:
1) 100 ...unb. and accelerate
2) 7...unb. and accelerate
Ek = 1/2mv^2
Ek = 1/2 * 30kg * 20^2 m/s
Ek = 6000J
Hope this Helps!
