SIGMA Fr=(mv^2)r
Nsin@=(mv^2)r
then from vertical component we find
Ncos@=mg
so N=(mg)/cos@
mg/cos@ * sin@ =(mv^2)r
tan@mg=(mv^2)r
do some work~~~~
v=sqrt(rtan@g)
did i do this right?
Homework Statement
A basin surrounding a drain has a shape of a circular cone opening upward, having everywhere an angle of 35 with the horizontal. A 25 g ice cube is set sliding around the cone without friction in a horizontal circle of radius R.
(a) find the speed the ice cube must have...
There are two forces on the 1.1 kg box in the overhead view of Fig. 5-37 but only one is shown. The figure also shows the acceleration of the box.

(a) Find the second force in unit-vector notation.
N i + N j
(b) Find the second force...
This is a fairly simple Question but I just can't figure it out. If there is an object and there are two forces that act on the 5 kg object (say this object is located on the origin of an sy plane) and F1= 25 N and points in the 0 degrees direction and the other force, F2= 15 N and points 60...
