There is 260g block on a 50cm -long string swings in a circle on a horizontal frictionless table at 50rpm What is the speed of the blockWhat is the tension in the string?
Lilgnome1205
The linear speed will be:
v = 2 * pi * r * f, where
r is circle radius,
f is rotations per second.
To calculate tension, we can use formula for centripetal force, which is:
F = mv2 / r.
This centripetal force will be the tension in the string.

How do you get a perpendicular line?
To make perpendicular lines, draw a horizontal line. Then using a compass or tracing around the edge of a curved object, draw one circle ( or just a semi-circle) so that it crosses the horizontal straight line in at least one point. Now rotate the compass or move the curved object to draw another circle (or semi-circle). This second circle (or semi-circle) must cross through the horizontal straight line as the first one did. It also must cross through the first circle (or semi-circle) at two points- above the horizontal straight line and below the horizontal straight line. Next, draw a straight line from where the two circles (or semi-circles) meet above the horizontal straight line through to where they meet below the horizontal straight line. You now have a line perpendicular to the first line.
