Question

Two vehicles are approaching an intersection. One is a 2500-kg pick up travelling at 14.0 m/s from east to west ( the -x direction), and the other is a 1500-kg sedan going from north to south ( the + y direction) at 23.0 m/s. What is the x components of the net momentum for this system?

Answer 1

Momentum along the x-axis:

$p_x = m_{pickup}υ_{pickup} \\ = 2500 \times (-14) \\ = -35000 \; kgm/s$
