I need a lot of help with Coulomb's Law and Electric Fields?? Need HELP! Homework Statement Here are 3 of the 25 questions the i did not understand, in regards with electric fields and Coulomb's Law. 1. A small object of mass 2.0 g and charge of 1.8x10^-7 C "floats" in an electric field...

sorry but i have one last question momentum and impulse... A boy with mass of 60 kg standing on a frozen lake throws a ball with mass of 10 kg at 10 m/s towards his worst enemy. His enemy with a mass of 50 kg catches the ball. What velocity does the ball have after being caught...

yea that was a typo 10 m/s not 10 mm/s.

I still need someone smart to explain 2 me momentum and Impulse throughly... 1. A hunter has rifle that can fire a.05 kg bullets with a speed of 900 m/s. A 40 kg leapord springs at him at 10 mm/s. How many bullets would the hunter need to stop the tiger dead in its tracks...

Which Has Greater Momentum? -------------------------------------------------------------------------------- The only formulas that were provided were 1. I =Δp 2. mΔv 3. I=FΔt 4. KE= 1/2 mv^2 5. PE= mgΔh 6. ΔPE= ΔKE 7. W= F*D 8. W= ΔKE Momentum Before Collision = Momentum After...
