Answer #1

The object moving towards left before the collision has more mass.

Because, in any collision momentum os consrved.

After the collision both objects are moving so, the direction of net momentum is towards left.

so, the momentum of the object moving left is more than momentum of the object moving towards right.

we know, momentum P = m*v

magnitude of velocity(v) is same for both objects.

so, mass of object moving towards left must be more than mass of the object moving towards right.

Two protons are initially moving towards each other with equal speeds in the laboratory. They continue to exist after experiencing a head-on collision that also produces a neutral pion of rest energy 135 MeV. If the protons and the pion are all at rest after the collision, find a) the initial kinetic energy of the protons, and b) the initial speed of the protons.

Two birds traveling at right angle to each other, collide, and hold on to each other during collision. The two birds have masses 3.04 kg and 8.78 kg. The smaller bird is traveling with the speed 18.1 m/s, and the larger bird is traveling with the speed 15.98 m/s. What is the speed of the two birds after the collision, to two decimal places? Hint: you need to make an assumption about the birds' initial direction of travel.
