Thanks for all of your help! It really is appreciated... it was just a question on our physics assignment that I could not find an answer for... but now I have thanks to all of you guys... :)
I have three questions that I am pretty confused about:
1. A slope rises 15m veritcally for every 40m of its length (in horizontal direction). A car of mass 1.25t travels a distance of 150m up the slope at uniform speed. Find the work done if the frictional resistance is 40N.
2. A...
Thanks for your working so far :smile: you make a lot more sense than my physics teacher, I have to tell you that! I had this strange idea that W=Fscos(theta) would be of use... and W=Fssin(theta) also...
I couldn't get my head around this problem... I'd like some input and some answers to aim towards please... I'm actually a pretty bright student, I just can't figure this out... maybe a blonde day lol? :smile:
A baseball of mass 55g leaves the pitchers hand at a speed of 48m/s. THe...
