Question

A car with a momentum (p) of 1,230 kg m/s has a mass (m) of 1,000 kg. What is its velocity (v)?

a) v = 1.23 m/s
b) v = 12.3 m/s
c) v = 123 m/s
d) v = 0.123 m/s

Answer 1

The velocity of the car with a mass of 1,000 kg and a momentum of 1,230 kg m/s is calculated by dividing momentum by mass, resulting in a velocity of 1.23 m/s. Hence, the correct answer is (a) v = 1.23 m/s.

Step-by-step explanation:

The question relates to the concept of momentum in Physics, specifically the relationship between momentum, mass, and velocity. Momentum (p) is given by the formula p = m * v, where m is the mass of the object and v is its velocity. To find the velocity of a car with a mass (m) of 1,000 kg and a momentum (p) of 1,230 kg m/s, we rearrange the formula to solve for v: v = p / m. Substituting the given values into the equation, we get v = 1,230 kg m/s / 1,000 kg = 1.23 m/s. Therefore, the correct answer is (a) v = 1.23 m/s.
