Sorry I was not able to reply early, I was at school, however I was able to figure out how to do the question, I realized that the radius of for the centripetal is 0.265 ( not the sphere, my bad...) then I made the equation mv^2/r equal to 27 ( since the string increased by 1.5 cm ), after that...

Oh, which equation should I use to find the speed of the sphere? Kind Regards

Also the question was to determine the speed of the sphere: my attempt of this was to try use the formula f=mv^2/r, however I can't seem to find the radius, I have uploaded a picture of the question as well.https://www.physicsforums.com/attachments/105425 Kind Regards

I was given a question relating centripetal force to solve A linear spring of negligible mass requires a force of 18.0 N to cause its length to increase by 1.0 cm. A sphere of mass 75.0 g is attached to one end of the spring. The distance between the centre of the sphere M and the other end P of...

Hey guys I'm a new member, I'm excited to share my ideas on physics!
