thanks for your help! :) i think I've worked out the answer using those equations

hi alphysicist and rohanprabhu, does h and r stand for radius? because i plugged in my data into both of your equations and did not get a right answer. my data is a bit different (m=1.1, r=3.2m, V1=3.6m/s, v2=8m/s) but the question is the same. i got around -50J to -60J using both your...

hi tiny-tim i haven't actaully tried it using your way.. which equations would you use?

i can't seem to edit my thread 2. Homework Equations ive tried using the equation of KE=1/2mv^2 and also W=1/2x^2 i've basically done everything i can without any progress. are there any other equations or ways of doing this type of question? thank you 3. The Attempt at a Solution

hi rohanprabhu, which equations did you use in ur calculation?

Homework Statement A 2.00 kg block situated on a frictionless incline is connected to a spring of negligible mass having a spring constant of 100 N/m. The block is released from rest when the spring is unstretched, and the pulley is frictionless. The block moves 23.0 cm down the incline of 37...
