Homework Statement In the figure, the orange line and the green line are perpendicular and intersect on the x-axis.Find the coordinates of P. http://tinypic.com/r/2wn7m2v/3 go here for the image please. Homework Equations slope-point formula, m1*m2=-1 FOR PERPENDICULAR LINES The...

No no, AB is congruent to DC and AH is congruent to HC. Sorry, I gave the wrong information. If i extend a line segment from A to D will it be congruent to DC

Geometry problem,very intersting, please check! Homework Statement In the figure,AH=HC and AB=DC,measure of angle A is 54.Whats the measure of the angle C? [PLAIN]http://img685.imageshack.us/img685/9144/gty.png Homework Equations Isosceles triangle theorem, altitudes ,medians ,angle...

Mass can not be written as 0 ,because mass is always constant in every aspect.

Thanks,but if it is like that The maximum height its 20m its half way 10m V^2=400-2*10*10 V=20m/s not correct

Momentum problem,please check! Homework Statement A 0.2 kg object is thrown vertically upwards at an initial velocity of 20m/s.Find its momentum when : a) it reaches its maximum height b) its momentum at the halfway of its maximum heightHomework Equations P=vm V^2=Vo^2+2ghThe Attempt at a...

Yes,you are right, thanks a lot.I got the correct answer

Right triangle problem,please check! Homework Statement In the figure,TN=NK, ST=12 and SN=\sqrt{69}.Find the length of TK. [PLAIN]http://img695.imageshack.us/img695/633/50042657.png Homework Equations Pythagorean Theorem The Attempt at a Solution Segment SN is the median of the...

a) correct b)T=mg that means that w=mg and they are equal. C)correct

When it applied 100N it should be 20.6m/s^2 upwards direction.

Homework Statement Find the acceleration of the object in the figure with mass 4 kg when it's applied a force of a)50N b)100N and which makes an angle of 37degrees.(sin 37=0.6,cos 37=0.8) [PLAIN]http://img97.imageshack.us/img97/5863/forceg.png Homework Equations F=maThe Attempt at a Solution...

Homework Statement A 4 kg object at height of 1 m is pushed with a velocity of 5m/s towards a spring.If the surface is frictionless and the spring constant is 200N/m,what is the maximum compression of the spring? PEspring=1/2kx^2 KEspring=1/2kx^2

yes it should be h=40 m to be equal. Because the KEi=3200 J and it should take the half of it to be equal,which means 1600J

can you please solve it xcvxcvvc?

It is like KEi+PEi=KEf+PEf and I need to find at which height they are equal yes it is thrown from y=0m
