She needed help with her physics class assignments, Anon dodged a bullet.
I have that at uni.
Hot girl asked me to come to her place after a party, said she "wanted help with her computer".
She actually wanted help with her computer.
Well? Did you help her?
The bullet weighs 10 grams and has a velocity of 330 m/s. It hits Anon in his 5 kg head and, because it's a rubber bullet, bounces off elastically. How fast is Anon's head moving after the collision?
Depends, how stiff is his neck?
0.66 m/s ?
Not quite, remember it's an elastic collision.
Ah, 1.317 m/s then.
