Thank you very much, I think I need that push of clarity which you provided. :approve:

You know the force and mass of the arrow, so you can calculate the acceleration: F=ma then using equations of motion for constant acceleration, meaning the force providing the acceleration doesn't change throughout the motion. v^2 = u^2 +2as, v=final velocity, u = intial velocity=0...

Homework Statement I've recently completed a experiment involving a Driven series RLC circuit. The potential difference across R " a variable resistor >> internal resistance of inductor" was measured. When calculating the current from the PD across R, should I include the internal resistance...

It's ok i continued with what i was doing and my error came out to be about right, effecting the the last numbers of significant figures. Thanks a lot dan

hello everyone, I've completed a experiment regarding torsional oscillations to determin the tortional ridgity in two types of wire. The final result is about what is to be expected but I am having trouble in calculating the error in my C " torsional ridigity" value. The formula used is...
