Question

Asked Oct 21, 2019

A 300 g block on a 58-cm-long string swings in a circle on a horizontal, frictionless table at 70 rpm.

What is the speed of the block?

What is the tension in the string?

Step 1

**Given information:**

Mass of the block (m) = 300 g = 0.3 kg

Length of the string (l) = 58 cm = 0.58 m

Revolution per minute (N) = 70 rpm

Step 2

We know that the angular velocity of the block is given by:

Step 3

The tension in the string is equal to the c...
