URGENTE!!! me ajudem prvr

Answer 1

LETRA A:
$V-V_0y-10.t\\ 0=100.0,60-10.t\\ 10t=60\\ \boxed{t=6s }$

LETRA B:
$S=S_0+V_0.t+\frac{a.t^2}2\\ S=0+100.6-\frac{10.6^2}2\\ S=600-5.36\\ S=600-180\\ \boxed{S=420m}$

LETRA C:
$A=Vx.t_{TOTAL}\\ A=100.0,79.(2.6)\\ A=79.12\\ \boxed{A=974m}$\\

LETRA D:
$t_{TOTAL}=6.2\\ \boxed{t_{TOTAL}=12}$
