31). During an explosion 3 particles fly apart, particle 1 of mass (2.00)kg moves out along the x axis at a speed of 10.00m/s, particle 2 of mass (3.00) kg takes off at an angle of 40 degrees above the negative x axis, and the third particle of mass (6.00) kg takes off at an angle of 35 degrees below the negative x axis. What are the speeds for particle 2 and 3 just after the explosion?

Answer #1

Given

m1 =2 kg

m2 =3kg

m3 =6kg

particle 1 of mass (2.00)kg moves out along the x axis at a speed of 10.00m/s

particle 2 of mass (3.00) kg takes off at an angle of 40 degrees above the negative x axis

----------------

the third particle of mass (6.00) kg takes off at an angle of 35 degrees below the negative x axis

--------------------------

During Explosion Momentum is conserved

Initial momentum =Final Momentum

Initially all particles are at rest ,so initial momentum =0

Since Momentum is conserved ,Final momentum is equal to Zero

A mass (m) moves along the x-axis with velocity 2v. Another particle of mass (2m) moves with velocity v along the y-axis. 1) If the two objects collide inelastically and merge, how much kinetic energy is lost to heat? 2) If instead they collide elastically and it turns out that m still moves purely along the x-axis, what is it's velocity in the final state? It may help to find the velocities of these particles in the center of mass...
