so does that mean the answer would be 9? (0.5)(21)=(0.2)(30)+(0.5)(x) 10.5=6+(0-5)(x) x=9??

ok here the question: jamal is at the state fair playing some of the games. at one booth he throws a 0.50-kg ball forward woth a velocity of 21.0 m/s in order to hit a 0.20-kg bottle sitting on a shelf, and when he makes contact the bottle goes flying forward at 30-0 m/s. A) What is the...

yes, My brother is going to UC to become a crime scene investigater, he says most of the classes he's taking are mostly research and forensics classes. He likes it a lot, he says it hard though.

ok so i need so serious help. the question is: A)what impulse occurs when an average force of 10 Newtons is exerted on a cart for 2.5 sec? I use the imp=Ft formula imo= (10n)(2.5sec) imp= 25 sec B)what change in momentum does the cart undergo? i don't know, is it the same force as...

Does anyone think that maybe we are doing to much for them?? Or too Does anyone think that maybe we are doing to much for them?? Or too little? I'm writing a paper on the topic, please give me your opinions...

HEY! I figured it out... you take the 16 which converts into Newtons times sec times 0.5 which gives you 8 Newtons!

yeah... okay so (8kg times 2m/s)- what's u stand for?? grrr i have a headache

hey, yes I know this but I'm not for sure how to put the numbers into the equation.. nice names lol :)

Momentum! eww A) what is the momentum of an 8-kg bowling bowl rolling at 2- m/s? I got this answer which in p=16 kg times m/s B)If the bowling bowl rolls into a pillow and stops in 0.5 sec, calculate the average force it exerts in the pillow? C)What is the average force that the pillow...
