Recent Axis Discussions:
What is its velocity at t = 6.0 s?
gives the acceleration a versus time t for a particle moving along an x axis. The a-axis scale is set by as = 12.0 m/s2. At t = -2.0 s, the particle's velocity is 10.0 m/s. What is its velocity at t = 6.0 s?

Ummm....that didnt work...any other suggestions.
How to do this physics problem involving a block on an incline?
A block of mass m1 = 2 kg rests on frictionless wedge of mass m2 = 10 kg whose surface is inclined at anmangle of = 40, as shown in the gure below. The wedge rests on a frictionless, horizontal floor in the earth's gravitational eld. In order to prevent the block from sliding down the incline, a force of magnitude F is applied to the wedge on the left side as shown, so that the wedge and block accelerate together with constant acceleration towards the right. We wish to calculate the required force F.
b) If the block is to refrain from sliding down the incline, what does the direction of its acceleration have to be? (Give a unit vector in the direction of the acceleration.) How does this compare with the direction of the total force on the block?
Wouldn't this just be in the positive x direction? Or would I have to include the x hat to make it a unit vector? This compares with the direction of the total force on the block, that it is also accelerated in the same direction to the right.
c) Given the direction of the total force in part (b), draw a diagram that shows the corresponding vector sum of forces in part (a).
Would I just put the x and y axis and then make a resultant?
d) From your diagram in part (c), calculate the magnitude of the total force on the block, in N.
M=sqrt(ax^2+ay^2). So I'd just calculate the components of x and y using the cos and sin.
e) What is the corresponding acceleration of the block, in m/s2?
So to find the acceleration i'd use F=masses*a, which would then be F/(M+m)=a. But I know that the formula a=g tan theta is the acceleration. So I'd plug it in and get 8.223 m/s. right?
f) What is the magnitude of the required force F, in N?
F=masses*a
F/(M+m)=a
F=(M+m) g tan α
F=(10kg+2kg)*9.8 tan(40°)
F=(12kg)*(8.223)
F=98.68N
Three charges are arranged as presented below. Q1 = 5.00 nC and Q2 = 2.00 nC are located on the y-axis and Q3?
A) Find the magnitude F of the electrostatic force on the charge Q3 on the x axis.
B) Find the angle of the above force. Use polar coordinates 0°< θ <360°.
C) Find the x component of the above force. Use + or - for direction.
D) Find the y component of the above force.
E&M help? Non uniformly charged rod, electric field?
A thin insulating rod 6.0 cm on an x axis, with 0 being at its center, has a non- uniform charge per unit length with lambda(x)= 7* 10^-6x, for lambda in coulombs and x in meters. Find the electric field of the rod on the axis for x> 3 (that is, outside the rod).
How would I go about solving this? I can't seem to integrate this, and I'm unsure about the limits of integration, which I believe should be 3 to x?
Constant Acceleration Question !!!?
A mass of 0.110 kg is initially at rest at an unknown position, xi, on the -x axis. It begins accelerating towards x=0, with a constant acceleration of 4.50 m/s2. As it passes x= -7.20 m its speed is 4.76 m/s. Calculate the total travel time from xi to x=0.00.
Calculate the speed of the mass as it crosses the origin, x=0.00.

What is your score on the political compass?
The political compass used to model different political positions.
The North/South axis is the social scale with south being Anarchism (No law) and north being Totalitarianism (Law is used to control everything you do)
The East/West axis is the economic scale with west being extreme Socialism (all wealth is distributed evenly by government) and east being extreme Capitalism (all wealth accumulates unevenly by lack of government)
