The .1 is not rational and I know how I got it but that's completely wrong, since .8 + .2 doesn't equal .1... I got confused with another problem I did earlier I guess.
So the initial velocity of an object thrown is the sum of the two final velocities of the vase and and the returning...
I'm not sure if I did this correctly, but here is what I did. (From what I understood from your explanation)
Football Vase
m .2 .8
v -3.9 2.6
I used m=.1
v= -6.5
Then got the momentum to equal .65
Then I did p/m=v .65/.2=3.25 m/s
So...
Someone throws his .20-kg football in the the living room and knocks over his mother's .8 kg antique vase. Ater the collision, the football bounces straight back with a speed of 3.9 m/s, while the vase is moving at 2.6 m/s in the opposite direction. a) How fast did Tyrrell throw the football? b)...
I'm not asking for the answers to my questions. What I'm asking is how to solve those individual questions. For example what formulas to use and if I should be converting from grams to kilograms. Well mostly on how to approach each question since I seem to be completely lost with momentun. I...
I need help with some momentum questions and the formulas i need to use to find the answers.
1. A car weighting 15,680 N and moving at 20 m/s is actd upon by a 6.4 x 10^2 N force until it is brought to a halt.
a. What is the car's mass? 1600Kg?
b. What is its initial momentum?
c. What is...
I'm unsure of what equations to use for this certain questions. I'd very much apreciated if anyone could tell me which equation is to be used for each individual problem. This is also a study review for an exam that's coming up very soon.
1. A bullet traveling 8.0 x 10^2 10^2 m/s horizontall...
I'm currently taking Physics in High School and having problems with Vectors.
I apologize in advance if this is the wrong forum to post this on but here it is...
I have to Diagram the vector combinations on graph paper and find the resultant and the equilibant.
