II zasada dynamiki Newtona
F=m*a
F=Fo+kt
(Fo+kt)/m=a
a= d2x/dt2
całka a dt=v
S- całka oznaczenie
SFdt= S(Fo+kt)dt
1/m S Fo* dt +1/m S kt*dt=V
(Fo/m)*t +k/2mt2 +Vo=V
S Vdt = F/2m*t2 + k/3m*t3 +Vot = x
podstaw dane i będzie git
4)
x(t) = 5 +2t + 4t3
dx/dt = v
v= 2+ 12t2
a= dv/dt
a= 24t
t=5s
a=120 m/s2
t=10s
a=240 m/s2
