Two vehicles are approaching an intersection. One is a 2300 kg pickup traveling at 13.0 m/s from east to west (the ?x- direction), and the other is a 1300 kg sedan going from south to north (the +y?direction at 21.0 m/s ).

Q1: Find the x -component of the net momentum of this system.

Q2: Find the y-component of the net momentum of this system.

Q3: What is the magnitude of the net momentum?

Q4: What is the direction of the net momentum?

Solutions

Expert Solution

We know that momentum is given by

---------------------------- Solution of part 1 -------------------------------

Find the x -component of the net momentum of this system

So X -component of net momentum of system is - 29900i

---------------------------- Solution of part 2 -------------------------------

Find the y -component of the net momentum of this system

So Y -component of net momentum of system is 27300j

---------------------------- Solution of part 3 -------------------------------

Find the magnitude of the net momentum of this system

------------------------ Solution of part 4 ------------------------------

direction of the net momentum

or direction of met momentum is 47.60 degree West to the North

as shown in rough fig.below.
