how do i find the concurrent forces of the ff:
given: F(sub 1)= 5 Newton,north; F(sub 2) 7 N at 30degreeof W; F(sub 3)= 10 N at 75 degree W of S

determine:1. F(sub 1) +F(sub 2) 2. F(sub 2)- F(sub 3) 3. F(sub3)+F(sub1)-F(sub 2)

what will i do...i dont know if its only a ordinary addition or substraction???please kindly help me with this

When glass bowl is dropped onto a hard surface, if often bounces a few times before it finally smashes. As the kenetic energy of the bowl is much reduced on each bounce, this seems counter intuitive. (and quite disappointing when you are raising your hopes that it will survive). If I were to catch the bowl the bounce before it finally smashed (assuming I knew which bounce that would be), would I notice any visible damage? If not, would be bowl be in an invisibly weakened state?

according to quantum physic anything can happen in the universe so long as it is for a short enough time. for example a positron and a electron will spontaniously exist and then concel each other out. momentarily breaking the conservation of mass/energy law. but how long are we talking about in second for this to happen?

i think that the time doesnt exist i mean that the time is the kinetic energy of every atom (E=U+Q) whatever the tempretur rises the time goes faster and whatever the tempreture falls the time goes slowly
so the energy and the matter is always chainging and ther is no past (becaus the matter-energy chainges from what it was) and no tomorow (becaus the matter-energy did not chainged)
and even there is no space-time system becaus if it does it would be the past,now and tomorow in a single moment
the meaning of trovelling tomorow is that making the chainges faster (the kinetic energy should rises to the matter-energy chainging faster than the other things)
and if this is true the aneshtines theory is falling
so what do you think? explain me

Two skaters on in-line skates, Lisa and Bart, are initially at rest. They push apart. and start moving in opposite directions. If Lisa's speed just after they push apart is 2.0 m/s and her mass is 85% of Bart's mass, how fast is Bart moving at that time?

In principle, anytime someone jumps up, the earth moves in the opposite direction. To see why we are unaware of this motion, calculate the recoil speed of the earth when a 77.0 kg person jumps upward at a speed of 2.30 m/s .
*If anyone has any clue how to do this please let me know*
THANKS GUYS!!! :)

A person kicks a ball a friend starts from rest, at the same point alongside the person,runs down the field at a constant acceleration toward the reciever. if the kicker kicks the ball at a 76.0 degrees above the horizontal, what acceleration does the friend need in order to arrive and tackle the reciever just as he catches the ball?

I have to find the percent error for this lab at school, but I can't find the absolute density for Carbon Dioxide. I've tried everything from contacting friends to Googling it. This is my last resort. If you found the density on a site, could you please list the site as one of your resources? Thanks.

A 7.50 kg block is resting on a horizontal surface, and is connected to a 5.50 kg mass suspended from a string passed over a frictionless pully. The surface is smooth, with no friction.

Would the tension on the string be 53.9 N?

I'm also suppose to find the tension of the string if the coefficient of friction is 0.190 on the surface, I have no clue on how to find that..A little help maybe?
