The momentum of a 12 kg dog racing to greet its owner is 37 kg m/s. What is the dog’s speed?
is Pb-mbvb=(12)(37)=?
no.
momentum=mass*velocity
velocity=momentum/mass=37/12 m/s

The formula for momentum is:
momentum = mass × velocity
Given:
mass (m) = 12 kg
momentum (P) = 37 kg m/s
To find the velocity (v), we can rearrange the formula as:
velocity = momentum / mass
Substituting the given values:
velocity = 37 kg m/s / 12 kg
Simplifying the expression:
velocity = 3.08 m/s
Therefore, the dog's speed is approximately 3.08 m/s.
To find the speed of the dog, we need to use the formula relating momentum and mass:
momentum = mass × velocity
Given:
mass of the dog, m = 12 kg
momentum of the dog, Pb = 37 kg m/s
We can rearrange the formula to solve for velocity:
velocity = momentum / mass
Substituting the values we have:
velocity = 37 kg m/s / 12 kg
Dividing 37 kg m/s by 12 kg:
velocity ≈ 3.08 m/s
Therefore, the speed of the dog is approximately 3.08 m/s.
