Final answer:
To find the mass of the zombie, given a momentum of 752 kg·m/s and a speed of 8.9 m/s, one must rearrange the formula for momentum to solve for mass. The calculation reveals that the mass of the zombie is 84.5 kg.
Step-by-step explanation:
The question involves finding the mass of a zombie, given its momentum and speed using the formula for momentum which is momentum (p) = mass (m) × velocity (v). To find the mass, we rearrange the formula to mass = momentum / velocity. In the given problem, the momentum is 752 kg·m/s and the speed is 8.9 m/s. Therefore the calculation for the mass (m) will be:
m = 752 kg·m/s / 8.9 m/s
m = 84.5 kg
Therefore, the mass of the zombie is 84.5 kg.
