Answer:
Distance, x = 5.7 m
Explanation:
We have,
Acceleration of the car is -8.7 m/s²
It is required to find how far will the car travel while coming to a complete stop if its initial speed was 10 m/s. Using third equation of kinematics to find it as :
So, the distance covered by the car is 5.7 m.
Hmm doesnt soujd familiar
Answer:
0.74 N/cm
Explanation:
The following data were obtained from the question:
Mass (m) = 3 Kg
Extention (e) = 40 cm
Spring constant (K) =?
Next, we shall determine the force exerted on the spring.
This can be obtained as follow:
Mass (m) = 3 Kg
Acceleration due to gravity (g) = 9.8 m/s²
Force (F) =?
F = mg
F = 3 × 9.8
F = 29.4 N
Finally, we shall determine the spring constant of the spring. This can be obtained as follow:
Extention (e) = 40 cm
Force (F) = 29.4 N
Spring constant (K) =?
F = Ke
29.4 = K × 40
Divide both side by 40
K = 29.4 / 40
K = 0.74 N/cm
Therefore, the spring constant of the spring is 0.74 N/cm
The answer is that it showed the scientist that on the area of the mantle from the subduction zones the slabs of the ocean floor remains or returns after such tectonic movement or earthquakes.
