Differentiate the components of position to get the corresponding components of velocity :


At <em>t</em> = 5.0 s, the particle has velocity


The speed at this time is the magnitude of the velocity :

The direction of motion at this time is the angle
that the velocity vector makes with the positive <em>x</em>-axis, such that

I think it's surface tension force
Answer:
The ring particles are made almost entirely of water ice, with a trace component of rocky material.
Explanation:
A ball is moving upwards and rightwards towards its peak. The ball .... since the only horizontal force acting upon it is a "left-ward" force.
Answer:
Option (1) f = 1
Explanation:
Formula for Frequency (F) = 1/t where t = Time in seconds.
F = 1/1
F = 1 hz ( hz or hertz is the unit for Frequency ).
