Question

If the momentum of a body is 10 kg x m/s when travelling at 20 m/s what is its mass? (remember: momentum=mass x velocity)

Answer 1

To find the mass of a body with a momentum of 10 kg × m/s and a velocity of 20 m/s, divide the momentum by the velocity to get a mass of 0.5 kg.

Step-by-step explanation:

The student asked: If the momentum of a body is 10 kg × m/s when travelling at 20 m/s what is its mass? To solve for the mass, we can use the formula for momentum, which is momentum = mass × velocity. Given the momentum (p) and the velocity (v), we can rearrange this formula to solve for mass (m) as follows: m = p / v. Plugging in the values given, we get m = 10 kg × m/s / 20 m/s, which simplifies to 0.5 kg. So, the mass of the body is 0.5 kg.

Answer 2

The mass of the body is calculated by dividing the given momentum (10 kg × m/s) by the velocity (20 m/s), resulting in a mass of 0.5 kg.

Step-by-step explanation:

To calculate the mass of a body given its momentum and velocity, we use the formula momentum = mass × velocity. Rearranging this equation to solve for mass, we get mass = momentum/velocity.

In this specific question, the momentum of the body is given as 10 kg × m/s, and the velocity is 20 m/s. Therefore, mass = 10 kg × m/s / 20 m/s = 0.5 kg.

Thus, the mass of the body is 0.5 kg when it is traveling at 20 m/s, and its momentum is 10 kg × m/s.
