The speed of an object in a mass-spring system is given under the function
Here,
m = mass
k = Spring constant
A = Amplitude
x = Position
When the position is at the equilibrium point (x = 0), the speed will be maximum, and could even be expressed as
So the correct answer is B.
Answer:
The speed of the raindrop is 11.55 m/s.
Explanation:
We need to find the speed of the rain in the "y" direction. We have:
: speed of the raindrop at 60° (vertical) =?
: speed of the car = 20 m/s (in the "x" direction)
Hence, the speed of the car and the speed of the raindrop are related by:
Therefore, the speed of the raindrop is 11.55 m/s.
