In an intense battle, gunfire can so concentrated that bullets from opposite sides collide in midair. suppose that a bullet (with mass =5.12 g moving to the right at a speed =208 m/s directed 21.3∘ above the horizontal) collides and fuses with another with mass m=3.05 g moving to the left at a speed =282 m/s directed 15.4∘ above the horizontal.

velocity

a).

direction

b).

kinetic energy

c).

Explanation:

Those kind of question have two typical questions inside to response the final velocity and the direction finding the angle and finally the kinetic energy so each the information you need can find there so

a).

solve to vf

b).

solve to β

c).

Final kinetic energy

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

answer: 31, 5556. 952 seconds
