Question

two particles A and B of mass 10 gram and 20 gram are moving with speed 12 metre per second and 15 metre per second respectively find the total linear momentum of the system of two particles if A and B move in the same direction and no in opposite direction

Answer 1

given, mass A=10 gram,velocity=12m/s

mass B= 20 gram,velocity=15m/s
formula, momentum=mass*velocity
p=m*v
p of A=10 *12=120gram metre per second
p of B=20*15=300gram metre per second
