    What equation to use for simple kinetics quesitons?

    So you have to derive for t right? This is what I got: t= sq root s-ut/0.5a This is correct? Really need to know this asap

    What equation to use for simple kinetics quesitons?

    I see, can you help me with how to know what equations to use for questions. Like I was confused for what equation to use for the second problem. Do I look for all the values I'am given with the values in all teh equatiosn then pick the one? Ik my quesitons is silly :P

    What equation to use for simple kinetics quesitons?

    Vf^2=vi^2+2a(d) v=sq root 30^2-2(9.81)(5) v= 28.3m THEN Solve for time using the equation: t=(v-vf)/a answer is 0.17seconds ;D THANKS FOR YA HELP MAN! :D

    What equation to use for simple kinetics quesitons?

    For the questions below, which kinematic equations would I use? I have already tried these on my own but can not find a way to match the answers with the answer sheet, the answers on the answer key are RIGHT, as they are approved by my teacher. Okey so the questions are 1) A baseball is...

    How Do You Calculate Speed and Uncertainty with Given Measurements?

    Homework Statement Hey there, I need some help with uncertainties and how to find the speed of a moving object. I have tried to solve the problem several times but my answer seems to be wrong. Formula for speed : v=d/t My uncertainties: 0.5cm (distance) and 0.5s for time. The uncertainties...
