Cart, Incline, Pulley, and a messed up Acceleration.
Fgx = mass x gravity x sin 26 Fgx = 3.6 x 9.8 x sin 26 Fgx = 15.465 This rounds off to 15.5 N, which is what I got. NOTE: cos 64 = sin 26- Some_Thing

Oops, I was using a url from hotmail. It showed up fine for me, but I guess that was because I was logged in at the time. Thanks.- Some_Thing

Cart, Incline, Pulley, and a messed up Acceleration.
The question and my work can be seen in the image below: http://img145.imageshack.us/img145/550/scan0001fgu.jpg The problem is that I am getting around 1 for acceleration, while the answer is 0.77. What am I doing wrong?- Some_Thing

How Much Work Does a Plane's Engine Perform to Reach 3200m at 65m/s?
Ah, I see, its one of those conservation of energy questions, isn't it? Change in Ek + Change in Ep = the correct answer (5.0 x 10^7) Thanks! One thing bugs me though. Shouldn't these two add up to 0?- Some_Thing

How Much Work Does a Plane's Engine Perform to Reach 3200m at 65m/s?
Homework Statement A 1500 kg plane, initially at rest, leaves an airfield and a short time later it is at an elevation of 3200 m traveling at 65 m/s. What is the minimum work done by the plane's engine in this time? (Ignore air resistance) Homework Equations W=Fd, F=ma, and most...- Some_Thing
