A car with a mass of 800. kg moving at 27.8 m/s has a momentum of 2.22 × 10⁴ kg.m/s. To have the same momentum, a car of 2400. kg would have to move at 9.25 m/s.
A small car with a mass of 800. kg is moving with a velocity of 27.8 m/s. The momentum (p) is the product of the mass (m) and velocity (v) of an object.
[tex]p = m \times v = 800. kg \times 27.8 m/s = 2.22 \times 10^{4} kg.m/s[/tex]
For a car of 2400. kg to have the same momentum, its velocity should be:
[tex]v = \frac{p}{m} = \frac{2.22 \times 10^{4} kg.m/s}{2400.kg} = 9.25 m/s[/tex]
A car with a mass of 800. kg moving at 27.8 m/s has a momentum of 2.22 × 10⁴ kg.m/s. To have the same momentum, a car of 2400. kg would have to move at 9.25 m/s.
