What is the momentum (in kg-m/sec) of a 910-kilogram car traveling north at 13.3 meters per second?
To find the momentum, we use the formula:
momentum = mass × velocity
First, we need to convert the mass from kilograms to grams:
910 kilograms = 910 × 1000 grams = 910000 grams
Then, we can calculate the momentum:
momentum = 910000 grams × 13.3 m/s = 12083000 grams-m/s
Since 1 kilogram is equal to 1000 grams, we can convert the momentum to kg-m/sec:
1 kg-m/sec = 1000 grams-m/sec
Therefore, the momentum of the car is 12083000/1000 = 12083 kg-m/sec.
To calculate the momentum (p) of an object, you multiply its mass (m) by its velocity (v).
Given:
Mass of the car (m) = 910 kg
Velocity of the car (v) = 13.3 m/s
The momentum (p) of the car can be calculated using the formula:
p = m * v
Substituting the given values into the formula:
p = 910 kg * 13.3 m/s
Now, we can calculate the momentum:
p = 12,083 kg-m/s
Therefore, the momentum of the car is 12,083 kg-m/s when traveling north at a velocity of 13.3 m/s.
