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?

(a) The momentum of a moving object is given by:

where m is the mass of the object and v is its speed. In this problem, the mass of the elephant is and its speed is , therefore its momentum is

(b) We can use the same formula to calculate the momentum of the tranquilizer dart, whose mass is and whose speed is :

we see that the elephant's momentum is much larger than the momentum of the dart.

(c) Again, using the same formula, the mass of the hunter is , his speed is , therefore his momentum is

the answer would be c. motion and direction

i hope this : )
