Hi so the question is as follows and I am not really good at physics, but I really want to improve and get better, so please DO NOT give me the answer, just push me in the right direction, thanks

{ The natural length of a spring is 10cm and its force constant is 5N/m. Now one side of the spring is fixed and the other side is connected to a ball, which has a mass of 6g. If the ball is moving in a horizontal circle with a uniform speed 10m/s, what is the total length of the spring when it is extended?}

I tried using Hooke's Law Force, the Centripetal Force equation and the Force equation (f=ma) but they don't seem to get me anywhere? Is there anything I am missing out on, or am i doing something wrong?

Please reply with useful advice.

The "cide" suffex means "killer"... So an insecticide is an insect killer and herbicide a herb (plant) killer. Pesticide is general to cover most pests, like insects, weeds etc..

 

You also get the same suffix with other words too, like biocide (killer of biological organisms), matricide (the killing of ones own mother), infanticide etc... Although infanticide is an act.... not an in can spay unfortunately. ;-)

thank you mucho
