What is the momentum of a 1.5 × 103 kilogram van that is moving at a velocity of 32 meters/second?
A. 46.9 kilogram meters/second
B. 4.7 × 103 kilogram meters/second
C. 4.85 × 102 kilogram meters/second
D. 4.85 × 104 kilogram meters/second
Momentum = 1.5*10^3 * 32 = 4.8*10^4.
To find the momentum (p) of an object, you can use the formula:
p = mass × velocity
Given that the mass (m) of the van is 1.5 × 10^3 kilograms and the velocity (v) is 32 meters/second, the momentum (p) can be calculated as follows:
p = 1.5 × 10^3 kg × 32 m/s
p = 4.8 × 10^4 kg·m/s
The correct answer is:
D. 4.85 × 10^4 kilogram meters/second
To find the momentum of an object, you need to use the formula:
Momentum = mass × velocity
In this case, the mass of the van is given as 1.5 × 10^3 kilograms, and the velocity is given as 32 meters/second.
To get the momentum, you simply multiply the mass by the velocity:
Momentum = 1.5 × 10^3 kg × 32 m/s
Let's calculate the momentum:
1.5 × 10^3 kg × 32 m/s = 48,000 kg·m/s
The momentum of the van is 48,000 kilogram meters/second.
Out of the given answer choices:
A. 46.9 kilogram meters/second
B. 4.7 × 10^3 kilogram meters/second
C. 4.85 × 10^2 kilogram meters/second
D. 4.85 × 10^4 kilogram meters/second
The correct answer is D. 4.85 × 10^4 kilogram meters/second, as it matches the calculated value of 48,000 kilogram meters/second.
