Question

A 900-kg giraffe runs across a field at a rate of 50 km/hr. What is the magnitude of its momentum? 18 km/hr

Answer 1

The correct answer is the one with 45000 kg*km/hr.
the formula is p = m*v
900 *50/hr giving u 45000
I know this is the correct answer because i have already turned it in and got a 100%.

Answer 2

Answer: The magnitude of momentum will be equal to 12,500 kg m/s.

Step-by-step explanation:

Momentum is defined as the product of the mass of the object and velocity of the object.

Mathematically,

`p=mv`

where, p = momentum

m = mass of the object ( in kg) = 900 kg

v = velocity of the object ( in m/s) = 50km/hr =
`\left((50* 1000)/(3600)\right)m/s`

Putting values in above equation, we get:

`p=900kg* \left((50* 1000)/(3600)\right)m/s=12500kg.m/s`

Hence, the magnitude of momentum will be equal to 12,500 kg m/s.
