Under the action of horizontal constant force F, the object with mass m starts to move along the horizontal plane from standstill. After t, the external force F is removed, and the object stops at the center after 2T (1) The resistance of the body (2) the total displacement of the body

(1)∑F=F-f=ma
v=at
∑F'=f=ma'
v=a'2t
(LIANLI)
So f = 1 / 3F
(2)s=1/2at²+1/2a'(2t)²=1/2×2/3×F/m×t²+1/2×1/3×F/m×t²
=1/2×(Ft²)/m
