Answer:
mass = 444.44 kg
Step-by-step explanation:
To calculate the mass of the truck, we can use the formula for momentum:
Momentum (p) = mass (m) × velocity (v)
Given:
Momentum (p) = 40,000 kg·m/s
Velocity (v) = 90 m/s
We can rearrange the formula to solve for mass (m):
m = p / v
Substituting the given values:
m = 40,000 kg·m/s / 90 m/s
m ≈ 444.44 kg
Therefore, the mass of the truck is approximately 444.44 kg.
