    Prove by induction that sum(1/2^i)<1 i =1 to n

    But isn't he supposed to prove by induction? And that's the general definition of induction that I know of. But I do see where you're coming from though.

    Math Math B.S. - no prior work experience

    a mathematics major can't be strictly limited to only teaching. Or at least I hope not. I would figure if you're majoring in math ed then teaching would be your direction. But if your majoring in mathematics I would figure that you would have a range of things that you could do

    Prove by induction that sum(1/2^i)<1 i =1 to n

    Is this prove by induction: like first proving that the statement is true for n=1 then prove its true for n+1?

    How Do You Calculate Initial Speed and Acceleration of a Slowing Truck?

    Oh wow interesting never thought of it like that. true

    How Do You Calculate Initial Speed and Acceleration of a Slowing Truck?

    Yea but if you do it that way, you still don't know Vo ? That's why I said solve for Vo and then plug in because then everything else can be filled in accept for a. then that's how you get acceleration.

    How Do You Calculate Initial Speed and Acceleration of a Slowing Truck?

    Why don't you try using this formulahttps://www.physicsforums.com/latex_images/90/905663-3.png and this formula https://www.physicsforums.com/latex_images/90/905663-4.png together. In the first equation solve for Vo then plug that equation in the second equation. You see?

    Coefficient of kinetic friction between the crate and the floor?

    I'm going to try to help because I need practice doing these problems so. Draw out a Free Body Diagram. g= 9.8 & m= F/g & ()=theta the horizontal Forces I got F= mgsin()+300N-Fk= 0 ( no acceleration) Solve for Fk (the friction force acting on the block) Fk=...
