Answer:
4020 N
Explanation:
First convert km/h to m/s.
54.0 km/h × (1000 m / km) × (1 h / 3600 s) = 15.0 m/s
Sum of the forces in the radial direction:
∑F = ma
F = m v² / r
F = (1250 kg) (15.0 m/s)² / 70.0 m
F ≈ 4020 N
Answer:
22.15 N/m
Explanation:
As we know potential energy = m*g*h
Potential energy of spring = (1/2)kx^2
m*g*h = (1/2)kx^2
Substituting the given values, we get -
(400)*(9.8)*(10) = (0.5)*(k)*(2.0^2)
k = 39200/2.645
k = 19600 N/m
For safety reasons, this spring constant is increased by 13 % So the new spring constant is
k = 19600 * 1.13 = 22148 N/m = 22.15 N/m
I dont think so but then again i dont live in florida.
1: Weather has a somewhat unpredictable pattern.
2: They can misinterpret the pattern of weather that looks like snow.
3: If they predict it early then the weather can change making there interpretation wrong.
Hope that helps a little bit. Please don’t report me I tried.
They’re falling toward earth & moving forward at about the same velocity. because the downward and forward forces are nearly equal, the astronauts are not pulled in any specific direction, so they float . <span>
