Final answer:
The mass of a truck with a momentum of 10,000 kg*m/s and a velocity of 4 m/s North is calculated by dividing momentum by velocity, which results in a mass of 2,500 kg.
Step-by-step explanation:
The mass of a truck given its momentum and its velocity. Momentum (p) is defined as the product of mass (m) and velocity (v) of an object, which can be represented by the equation p = m * v. To find the mass of the truck, we rearrange the formula to m = p / v.
Given the momentum of the truck is 10,000 kg*m/s and the velocity is 4 m/s North, the mass (m) is calculated as follows:
m = p / v
m = 10,000 kg*m/s / 4 m/s
m = 2,500 kg
Therefore, the correct answer is c) 2,500 kg.
