    Movement between two blocks

    Ok, so my Ff that I got is the minimum force required to move the blocks at all? But then I don't understand how I'm supposed to solve for anything else if I'm not given any other values?

    Movement between two blocks

    Ok so first I drew the blocks on top of each other and found both normal forces. The normal force acting on block A (Na) is 34.335 N, and the normal force acting on block B (Nb) is 73.575 N. Because P is acting on A, you can find the friction force by multiplying the friction coefficient (0.4)...

    Finding net force from position vector

    wow this was so helpful. It makes so much sense now.

    Finding net force from position vector

    I understand that you have to take second derivative of r to find a Doing it in dr^2/dt^2 = 6(0.042 m/s^3) t*i - 0.196 m/s^2 k, and then multiply (2.48*10^5) to 6(0.042*9.5) and to -0.196 However, my homework platform is NOT accepting 593712 N (or any rounding of it)for i vector and -48608 (or...
