1. Homework Statement
A particle of mass m is initially at rest at x = 0.
It is acted upon by a force F = A cosh (\beta t) (1)
A) Show that at very small values of t, the position is approximately given by x(t) = \frac{1}{2}\frac{F_0}{m}t^2 (2),
where F_0 is the force...

1. The problem is the following:
Starting from stillness @ t = 0, we are looking for the acceleration @T=0 of the 2 wheels (rolling without slip, in particular in point P4 we have a gear wheel contact so we can have that the reaction R2y of the plane could be also in direction y2, in this case...
Are two forces in the equation different forces?
I heard the force in the second equation is like impulsive force. The concept is nebulous to me can someone also elaborate further?
f=ma
f= mxΔv/t
