Final answer:
The velocity of the vampire after it tackles the werewolf is found using the momentum formula and is calculated to be 14.61 m/s.
Step-by-step explanation:
To find the velocity of the vampire after it tackles a werewolf, we use the formula for momentum, which is the product of mass and velocity. The formula is p = m × v, where p is momentum, m is mass, and v is velocity.
In this question, the momentum of the vampire is given as 1052 kg·m/s, and its mass is given as 72 kg. To find the velocity, we rearrange the formula to solve for velocity:
v = p / m
Substituting the given values:
v = 1052 kg·m/s / 72 kg = 14.61 m/s
Therefore, the velocity of the vampire is 14.61 m/s.
