Answer:
Explanation:
Hello,
In this case, since the average velocity is computed as the change in the distance divided by the elapsed time:
As 4 m were displaced in 16 seconds, the average speed turns out:
Best regards.
Answer:
Height, h = 13.02 meters
Explanation:
It is given that,
Spring constant of the spring, k = 750 N/m
It is compressed by 35 cm relative to its unstained length, x = 35 cm = 0.35 m
Mass of the object, m = 0.36 kg
When the spring is released, the mass is launched vertically in the air. We need to find the height attained by the mass at this position. On applying the conservation of energy as :
Energy stored in the spring = change on potential energy
h = 13.02 meters
So, the mass will reach a height of 13.02 meters. Hence, this is the required solution.
For this case, what we can do is use the Pythagorean theorem to find the magnitude of the displacement of the car.
We have then
From here, we clear the value of d.
We have then:
Rewriting:
Answer:
The magnitude of the car's displacement is:
d = 20 miles
It would be Thermal Radiation
