What is the momentum of a 2000 pound car traveling at 30 miles per hour? Answer in metric units
To find the momentum of the car, we need to first convert the pound and mile units to metric units.
1 pound is approximately equal to 0.4536 kilograms.
Therefore, the mass of a 2000 pound car is 2000 * 0.4536 = 907.2 kg.
1 mile is exactly 1.60934 kilometers.
Therefore, the speed of the car in metric units is 30 * 1.60934 = 48.2802 m/s.
The momentum of an object is given by the formula:
momentum = mass * velocity.
Substituting the given values, we get:
momentum = 907.2 kg * 48.2802 m/s = 43795.6 kg·m/s.
Hence, the momentum of the 2000 pound car traveling at 30 miles per hour is approximately 43795.6 kg·m/s.
