Respuesta :
The momentum of the first truck is 40,000 kgm/s.
The velocity of the second truck with equal momentum is 28.57 m/s.
The given parameters:
- Mass of the first truck, m = 4000 kg
- Velocity of the first truck, v = 10 m/s
- Mass of the second truck, m = 1,400 kg
What is momentum?
- Momentum is defined as the product of mass and velocity.
The momentum of the first truck is calculated as follows;
P = mv
P = 4000 x 10
P = 40,000 kgm/s
The velocity of the second truck with equal momentum is calculated as follows;
[tex]P = mv\\\\v = \frac{P}{m} \\\\v = \frac{40,000}{1,400} \\\\v = 28.57 \ m/s[/tex]
The complete question is below:
- A 4,000-kilogram truck travels in straight line at 10.0 m/s, What is its momentum?
- A 1,400-kilogram car is also traveling in a straight line. Its momentum is equal to that of the truck in the previous question. What is the velocity of the car?
