No matter how many times i do it, i seem to be doing something wrong :| 1. The problem statement, all variables and given/known data A wet bar of soap (150 g) slides without friction down a ramp (2.0 m) long inclined at 7.3degrees. How long does it take to reach the bottom? Neglect friction. & How would this change if the soaps mass were 250 grams? 2. Relevant equations stated below>> 3. The attempt at a solution So i tried to calculate Fnet using sine. since Fg=1.5kg*9.8=14.7N Then i did, sin7.3=x(aka fnet) / 14.7 x = 12.5 Then: Fnet = ma 12.5=0.15a a=83.3 then d=vit+1/2at^2 2=0+1/2(83.3)t^2 2/(1/2*83.3)=t^2 Suqareroot(0.048)=t t=0.219 or around there. However the answer is 1.8 seconds? Can anyone help me see what im going wrong? Any help is much appreciated, thanks. EDIT::: Sorry, nevermind, turns out my calc was in radian mode -facepalm- Good grief.
