I tried changing the equations into logarithm form: log(5X) = 15log(1+X) and afterwards i still can't solve for X Yeah the book also did the same (numerical approximation). I thought there's a way(s) to do it other than that :/

5X = (1+X)^15 What to do with this kinds of problems? How do I solve for X? I encounter this problems on engineering economy(Annuities)... I tried doing logarithms but no success.

From the problem you can tell what is the initial velocity and the acceleration, right?

@sammy: Great! I got it now thanks. What I did is I made the incline my x-axis (hint). With that I now have: Q = 600∠-30 W = 200∠-120 and then: Qx = 519.62 Qy = -300 Wx = -100 Wy = -173.21 and since R is parallel to the incline which is now the x-axis therefore ΣRy = 0 = Qy + Wy + Py or...

Homework Statement [/B] The block shown in Fig. P-223 is acted upon by its weight W = 200lb, a horizontal force Q = 600lb and the pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the incline thereby sliding the block up it. Determine P and R. Hint...
