Hi there! Thank you in advance! I am working on physics 11 right now and it would be grerat if I could get some help on a few homework questions. I've already worked through them a bit but I'm really not confident about my answers so I guess I'm looking for confirmation or corrections. Thank you for your time :D A 2.0kg block of wood starts at rest and slides down a ramp. Its initial height is 12.0m. If the final velocity of the block is 13m/s, determine the energy of this system that has been turned into heat. I did total final energy minus total initial energy and got 66.2 J as my answer. 2. The coefficient of kinetic friction between a 3.0kg wooden block and the surface on which it is moving is 0.28. Determine the work required to move the block 12m along this surface. My work: W=Fnet d W=(0.28)(3)(9.8)(12) W=98.76
I need basic explanations
