A 0.106 kg rock is attached to a 2.02 m long string and swung in a horizontal circle at a speed of 29.4 m/s. Find the tension in the string. Neglect the effect

Question

Of gravity.

Answer 1

The tension in the string must equal the centripetal force.

 

T = F_c = mv²/r = (0.106 kg)(29.4 m/s)² / (2.02 m) = ? N

 

You can finish from here.
