yay i got it right thanks!
Physics
a mass (m1) on a smooth horizontal surface, connected by a thin cord that passes over a pulley to a second block (m2), which hangs vertically. If the acceleration is .098 m/s^2 and m1 is 1.0 kg how much must m1 must be to keep it at this acceleration I got 99 kg could you plea...

oh wow so I\'m not sure how to do this if the net force in the y direciton is zero...
Physics
wait so if downards was negative the force of gravity on the first block would be -85 N the force of gravity on the seocnd block is - 30 N for problem (a) and the force of tension is equal and opposite to the force of gravity on the second block and is 30 N net force in y dire...

I have a question 26. A box weighing 85 N rests on a table. A rope tied to the box runs vertically upward over a pully and a weight is hung form the other end. Detrmine the force that the table exerts on the box if the weight hanging on the other side of the pully weighs (a) 3...

Is mass the one and only thing that produces a gravitional force???
physics
take a satalite going around the earth... what allows us to say net force (radial) = Fg = Fr = ma were the Fg is the force of gravity exerted on the satalite were Fr is radial force and ma is the mass and acceleration of the satalite ok I understand newtons second law but what...
physics
"The actual value of computed g, assuming no drag, also varies somewhat over the earth's surface due to the earth's spin (which causes a latitude-dependent centrifugal force to get subtracted), lack of a perfect spherical shape of the earth, and the proximity of v...

Hi i'm doing that lab were you attach a weight to a tape which is also through a timer that puts marks on the tape at a given time interval ok I'm asked why is gravity different than on Earth? I don't rember the physics answer behind it I remeber Fg = G((m1 m1)/r^2...
physics
ok i saw the responses thanks still a little bit confused ok what variable is different or varaies in the sitations were you to walk say down a hill and feel that it is easier and when walking up a hill which is harder
