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?

Step-by-Step Solution:

Step-by-step solution In this problem a hunter fires a tranquilizer dart to a elephant which is been missed so, calculate the momentum of elephant charging a hunter at certain speed and compare the elephants momentum and the hunter momentum as per the given data respectively: Step 1 of 4 The linear momentum p is defined as the product of mass m and velocity v of an object or particle, Step 2 of 4 (a) Now, if pe is the momentum, then this is expressed as, Substitute for mass of elephant and for speed of elephant . Hence, the momentum of an elephant is .
