Solution
Part A
The momentum of an object is given by the product of its mass and velocity. The x-component of the momentum is associated with the pickup truck.
Given: Mass of the pickup truck (m1) = 2500 kg Velocity of the pickup truck (v1) = -14.0 m/s (The negative sign indicates that the truck is moving in the -x direction)
The x-component of the momentum (px) can be calculated as follows:
px = m1 * v1 px = 2500 kg * -14.0 m/s px = -35000 kg*m/s
So, the x-component of the net momentum of the system is -35000 kg*m/s.
Part B
The y-component of the momentum is associated with the sedan.
Given: Mass of the sedan (m2) = 1600 kg Velocity of the sedan (v2) = 25.0 m/s
The y-component of the momentum (py) can be calculated as follows:
py = m2 * v2 py = 1600 kg * 25.0 m/s py = 40000 kg*m/s
So, the y-component of the net momentum of the system is 40000 kg*m/s.
