ah so would that mean the force is 0, bc there is no acceleration? that's the only thing i can come up without of the first law clue you are giving me

Homework Statement A ball is shot horizontally at a speed of 10 m/s from a height of 2 meters. How long is the ball in the air and how far horizontally does it travel before it hits the ground. Homework Equations V2 Equation The Attempt at a Solution I am assuming I need to find...

ok so if you double the mass, then you double 1176 and that is the second part of the answer correct?

so 200kg(9.8) = 1960.. times that by 0.6 and you get 1176?

so would that be 9.8 m/s2 times 0.6?

Homework Statement A heavy box (200.0 kg) is sitting still on a warehouse floor, despite the efforts of a worker to push it (with a force of 300.0 N). If the coefficient of static friction between the box and the floor is 0.6, what is the friction force between the box and the floor? What is...

Awesome, thank you so much delphi you are awesome!

Would it be F=6kg(1.7), because that would give you the force that must be used in order to get the 6kg block to accelerate at 1.7 thus what the 3 kg block must be pushing with?

OK, so that would mean F=9kg(1.7m/s2)... this gives an answer of 15.3 N. So if block 1 must be using this force, how do you take that force and figure out what the 3 must be using on the 6?

ok, so I did 17N = 10kg(a). Therefor, a must equal 1.7 correct? Then, I plugged 1.7 into F=4kg(1.7) which gave me 6.8. I thought this would be correct for portion (a) but it wasn't. I did not attempt the second part of the question because this was wrong. Does this mean that only the 3kg...

thanks for the help, i am having trouble following what you are saying could u give me a starting point so I can go from there and finish the problem. Physics is not my cup of tea I can't visualize this in my head at all!

Homework Statement Blocks with masses of 1 kg, 3 kg, and 6 kg are lined up in a row on a frictionless table. All three are pushed forward by a 17 N force applied to the 1 kg block. (a) How much force does the 3 kg block exert on the 6 kg block? (b) How much force does the 3 kg block exert...
