Im really just searching for a general explanation!
If you are solving a pretty standard left hand side differential equation, but a diracs delta function on the right hand side. I am abit confused about how to interpret this.
If this is the case for the right hand side:
r(t) = Diracs (t)...
Yes well I have been trying too solve this without thinking about the table. But I was thinking of something, since I know that the hypotenuse is 0.5m. If you imagine a right-angled triangle, one side that illustrates the difference in height and the other traveled in x-direction.
But still I...
Homework Statement
Okey, so the problem started with a ball in circular motion on a table (xy-plane, seen from above). Eventually the rope that held the ball snapped and the ball continued on (no friction/air resistance) with constant velocity in x-direction. Gravity working in negative...
Hi,
I got a ball in a circualar motion on a frictionless table and in a uniform circle.
I need to calculate the tangential acceleration and radial acceleration.
What I know:
Radius: 0.4m
Tangential velocity: 0.50m/s^-1 (constant)
Are theese formulas right for this problem?
Radial...
Hi,
I need some help, I have a system with 3 cylinders (I got the center of mass for the system). Now I need to calculate the moment of inertia for the system.
I have tried to find some examples or general information, but they all show when the axis either is centered within the object or...
Okey,
so I have calculated that the net force for the circular motion is 4N... -4(j) if we are at angle zero position.
Now correct me if I am wrong on this:
When the angle is 0, that is when the ball is on the right side of origin on the x-axis.
The force is then pointing too origin and that...
An object moves in the xy-plane in a uniform circular motion. We know that there is two forces action upon the object. One we have that is F1, F2 is unknown. Both vectors
speed : 4m/s
radius : 4m
mass : 1kg
F1 : 10 i N (i as in x-direction vector)
F2 : ? (bound to be in the xy-plane)
How do I...
