8.1 Exercise 7

Avg difficulty 2.5

(a) Calculate the momentum of a 2000-kg elephant charging a hunter at a speed of 7.50 m/s7 . \text{50 m}/\text{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\text{600 m}/\text{s}. (c) What is the momentum of the 90.0-kg hunter running at 7.40 m/s7 . \text{40 m}/\text{s} after missing the elephant?
