Question

What is the momentum of a 2000-kg elephant charing a hunter at a speed of 7.50 m/s?

Answer 1

`15000\ \text{kg m/s}`

Explanation:

Momentum `P` of elephant of mass `m=2000\ kg` & running at a speed of `v=7.5\ \text{m/s`

`P=mv`

`2000\cdot 7.5`

`=15000\ \text{kg m/s}`

Answer 2

Momentum `color(blue)(p = m * v = 2000 * 7.5 = 15,000` `kg. m.s^-1`

Explanation:

It's a term that describes a relationship between the mass and velocity of an object, and we can see this when it is written in equation form, p = mv, where p is momentum, m is mass in kg and v is velocity in m/s.

Because momentum is a vector quantity, this means it has both magnitude and direction.

Given `m = 2000 kg, v = 7.50` `ms^-1`

Momentum `color(blue)(p = m * v = 2000 * 7.5 = 15,000` `kg. m.s^-1`
