Homework Statement
You slowly lift a box of books from the floor and put it on a table. Earth's gravity exerts a force, magnitude mg, downward, and you exert a force, magnitude mg, upward. the two forces have equal magnitudes and opposite directions. It appears that no work is done, but you...
Homework Statement
A 32-N force acting at 25 degrees and a 36-N force acting at 75 degrees act concurrently on point p. What is the magnitude and direction of a third force that produces equilibrium at point P?
The teacher said that we had to know higher math then algebra 1 for this...
Homework Statement
The weather pictures you see every day on TV come from a spacecraft in a stationary position relative to the surface of Earth, 35,700 km above Earths equator. Explain how it can stay exactly in position day after day. What would happen if it were closer? Farther out...
thats what i told them except for the straight line thing. So the way i found force was right. Thats how i told them to do it. I am not sure why they thought they had to find to friction. You have been the biggest help ever by the way.
b) what force must the track exert of the tires to produce this acceleration.
for this i used the fnet=mac
fnet=615kg(9.65)
fnet=5934.75
after i told the other class mates that were saying there was no acceleration at all how you do the...
Homework Statement
Well were making a poster about circular motion. I was wondering if you guess had any other important things i should add on there about it.
Homework Equations
ac=v^2/r
fnet=mac
The Attempt at a Solution
So for the circular motion the subtopics in the book are...
ok so the teacher said that we use r=0.153m so to find the centripetal acceleration. ac=v^2/r so to find velocity i do distance/time so would it be 0.153m/2010m/s. would that be how i find velocity. because i also have a circular motion equation for velocity which is v=delta r/ delta time
