A chickadee with a mass of 12 g sleeps on a stationary branch. What is its momentum?
A. 0 kg*m/s
B. 2 kg*m/s
C. 36 kg*m/s
D. 120 kg*m/s
I think it is A but can someone check
p = mv = 12g * 0m/s = 0g-m/s
Well, let's think about it. Momentum is calculated by multiplying an object's mass by its velocity. Since the chickadee is sleeping, we can assume its velocity is zero. So, the answer would indeed be A - 0 kg*m/s. However, I must say, that chickadee must be quite the expert at staying still and maintaining a perfect balance on that branch!
To calculate the momentum of an object, you need to multiply its mass by its velocity. However, since the chickadee is sleeping, its velocity is considered to be zero.
Therefore, the momentum of the chickadee would be 0 kg*m/s.
So, your initial assumption is correct. The answer is A.
To find the momentum of an object, you need to multiply its mass by its velocity. However, since the question states that the chickadee is sleeping on a stationary branch, we can assume that its velocity is 0 m/s.
Therefore, the momentum of the chickadee can be calculated as:
Momentum = mass x velocity
Momentum = 12 g x 0 m/s
To perform the calculation, you need to make sure that the units are consistent. Since the given mass is in grams (g), and momentum is typically measured in kilogram-meter per second (kg*m/s), you need to convert the mass to kilograms (kg).
1 g = 0.001 kg
So, the mass of the chickadee in kilograms is:
12 g x (0.001 kg / 1 g) = 0.012 kg
Now, you can calculate the momentum:
Momentum = 0.012 kg x 0 m/s
Momentum = 0 kg*m/s
Therefore, the answer is A. The momentum of the chickadee is 0 kg*m/s.
