Problem 1PE

(a) Calculate the momentum of a 2000-kg elephant charging a hunter at a speed of 7.50 m/s . (b) Compare the elephant’s momentum with the momentum of a 0.0400-kg tranquilizer dart fired at a speed of 600 m/s . (c) What is the momentum of the 90.0-kg hunter running at 7.40 m/s after missing the elephant?

Part (a)

Step 1 of 5:

The momentum of an object is the product of the mass of the object and the speed of the object. We are going to calculate the momentum of an elephant.

The mass of the elephant

The speed of the elephant
