    Programs BS/MS in CS or BS in CE/CS (combined major)

    Good point. I do want to attend graduate school, and I am more interested in computer science, but I feel that the computer engineering degree might make it easier to penetrate hardware-centric fields like robotics.

    Programs BS/MS in CS or BS in CE/CS (combined major)

    I am a freshmen at Northeastern University. Right now, I am in the College of Engineering, where I am on track to earn a combined degree in computer science and computer engineering. However, I could easily transfer to the College of Computer and Information Science, where I could earn a...

    How heavy does a roller coaster rider feel?

    One more question: I should still factor in his weight due to gravity, correct? That is to say, since he weights 784 N, I should add that to how heavy he feels. No?

    How heavy does a roller coaster rider feel?

    Homework Statement A roller coaster rider has a mass of 80 kg and is riding in the coaster shown in the figure. If the vehicle has a speed of 10.0 m/s at the top of the first hill (assume same height as the top of the circle above Point A): a) how "heavy" does the rider feel at point A? b)...

    Find the Total Current in a Single Loop Circuit

    Homework Statement Find the current flowing through the circuit. http://wildedge.zxq.net/IMG.jpg Homework Equations Amps=Total Voltage / Total ResistanceThe Attempt at a Solution (20 + 12 + 12 + 3) / (10 + 5 + 30 + 40 + 20 + 15)=0.39A I'm almost certain that this is wrong. I don't even know...

    Acceleration of a proton in an electric field

    Okay. I thought that by +e the problem meant that the electron and the proton were a pair (as in a hydrogen atom). They just meant that the charge on a proton is the same as the charge on an electron, but positive. Thanks for clearing that up.

    Acceleration of a proton in an electric field

    Homework Statement A proton (+e) accelerates from rest in a uniform electric field of 640 N/C. At some later time, the proton's speed is 1.20 x 10^6 m/s. Find the acceleration of the proton. The mass of a proton is 1.67x10^-27 kg. Charge on a proton is +1.6x10^-19C. Homework Equations...

    How much ice melts when a projectile is fired at it?

    Homework Statement Newt needs to melt some ice, so he fires a test projectile (0.025 kg) at 30.0 degrees C at a speed of 240 m/s into a large block of ice at 0 degrees C, in which it becomes embedded (comes to rest). Approximately what mass of ice melts? (i.e. ignore the heat lost by the...
