    MATLAB Help with MATLAB Error: "Subscript Indices Must Be Real Positive Integers

    http://i.snag.gy/FBeLq.jpg I've figured out the first part, (a), it's the second part (b) that's confusing- I've tried re-arranging the plot() function and also tinkering with y1 and y2 rather than y(t), as I get the error: "Subscript indices must either be real positive integers or logicals."...

    Roller coaster change in acceleration?

    There seems to be a second part to the problem, which I'm rather confused on as well; could someone provide any hints? (b) What force will Bond feel (presuming he survives past Point B) at Point C where the radius of curvature has been reduced to 15.0 m and is 30 m above point B (i.e., what...

    Roller coaster change in acceleration?

    Homework Statement You have taken a job as senior hench-person with Dr. Caasi Notwen, arch-nemesis of James Bond. As with all of Bond’s enemies, Dr. Notwen would like to develop an overly complicated method of dispatching the British super-spy, so he has tasked you with designing a...

    Voltage, electricity and transformers question?

    So far I have a few variables mapped out, and apparently, the first equation and 'part' figured out: I = 100A, Vp = 22kV, r =2mm, Equationing: Part 1 VsIs = VpIp(.95) Is = [(22)(100)(.95)] / [240kV] = 8.708A (secondary transformer output current apparently) Part2 Power Loss...

    Voltage, electricity and transformers question?

    Homework Statement An electric power plant generates electricity @ 22 kV and 100 A. The voltage is stepped up to 240 kV before being transmitted to a city 15 km away over a copper wire that has a radius of 2 mm. Energy is lost in heating the wire during transmission. If the transformer...
