Well, anyways, i'll tell u what ever i get tomorrow.

well, I am not really sure, u might have a point there. I have physics tomorrow afternoon, so i'll print this out and ask the teacher tomorrow. I really want to know the answer of this :D i'll let u know tomorrow if anything comes up. ( by the way, is this grd12 physics or what?)

this problem needs alittle understanding about momentum, something i don't understand that much. A ball of mass 600g is moving 12 m/s[e]. The ball suddenly explodes into three equal mass pieces. One piece heads north at 6m/s, the second piece heads west at 5m/s. Determine the velocity of the...

No, i didnt solve for Pi. i used an equation that works with elastic collision only and has to have V2 as 0. so i change the frame of reference to be 0, and changed it back after i got the answer.

Well, its been an hour since i posted the question. I got the first part for elastic collision right.. but the inelastic i can't solve it, can someone show me how to solve it, because then tomorrow i have a lab that has to do with collisions and i have to understand this. Thanks a lot

Im not really good at elastic and inelastic collisions,, can someone help me with collisions please. In the movie the fast and the furious, a 1350Kg tuned up Civic moving at 15m/s hits a 1450Kg car moving at 12m/s. Determine the final velocity of the cars if (a) the collision was elastic AND...

Well i tried to solve for K just what u wanted, and i did. i will put down my calculations.. look over it just to make sure that what i did was correct or not. m = 0.01g d = 1.6m to find K, u use the equation, Ee = 0.5kx^2, u need Ee. Ee = Ek Ek = 0.5mv^2 u have the mass, u need the...

A ball of mass 450g lands on a spring with k = 5.0E3 . The ball was originally dropped from a height of 2.50 m. Determine the maximum compression of the spring AND the velocity it will leave with after bouncing of the spring. Thank u for helping
