What is the momentum of a car with a mass of 1,900 kg moving at a constant velocity of 20 m/s?
(1 point)
O 38,000 kg.m/s
O 95 kg.m/s
O 0 kg.m/s
• 40,000 kg.m/s
The momentum of an object can be calculated using the formula:
momentum = mass x velocity
Given that the mass of the car is 1,900 kg and the velocity is 20 m/s, we can substitute these values into the formula to find the momentum:
momentum = 1,900 kg x 20 m/s = 38,000 kg.m/s
Therefore, the correct answer is:
O 38,000 kg.m/s
To find the momentum of a car, you can use the formula:
Momentum = mass × velocity
Given that the car has a mass of 1,900 kg and is moving at a constant velocity of 20 m/s, we can substitute these values into the formula:
Momentum = 1,900 kg × 20 m/s
Calculating the product, we find:
Momentum = 38,000 kg⋅m/s
Therefore, the correct answer is:
O 38,000 kg.m/s
To find the momentum of an object, you need to multiply its mass by its velocity. The formula for momentum is:
Momentum = Mass × Velocity
In this case, you are given that the mass of the car is 1,900 kg and its velocity is 20 m/s. So, you can calculate its momentum:
Momentum = 1,900 kg × 20 m/s
= 38,000 kg.m/s
Therefore, the correct answer is "38,000 kg.m/s" (Option O 38,000 kg.m/s).
