Here is a lot of free P O I N T S. My battery is gonna die and I’m gonna get rid of bc of all the W E I R D people on here. So take this as my parting gift. Peace out people. And say hi to joy123333 for me. She’s a C*** who keeps deleting my questions. And if I get banned from then I D C bc I’d rather be checking me emails than be on here and watch JOY delete my questions. Hope y’all have a nice life :)

Explanation:

lolthat's the attitu de

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
