Answer on Mechanics | Relativity Question for yasmina
Fm - Fres = ma
where Fm is the force which
motor pushes and Fres is a resistive force.
a = (Fm - Fres)/m =
(2.72*10^3 - 1.76*10^3) / 1384.9 = 0.693 m/s^2.
The equation for displacement
S = V0*t & + (at^2)/2, V0 = 0.
S = (at^2)/2 = (0.693*17.3^2)/2 = 103.7
