Question

ME AJUDEM POR FAVOR!!!​

Answer 1

Explicação:

vf=vi+at

a) 10=0+a*5 -> 10/5=a -> a= 2m/s²

b)120= 30+a*25 -> 120-30=a*25

90=a*25 -> 90/25=a -> a=3,6ms²

c)720=120+a*32 -> 720-120=a*32

600=a*32 -> 600/32=a -> a=18,75m/s²

d)1024=312+a*52 -> 1024-312=a*52

712=a*52 -> 712/52=a -> a=13,69m/s²

e)152=45+a*15 -> 152-45= a*15

107=a*15 -> 107/15=a -> a =7,13m/s²

f)30=0+a*2 -> 30/2=a -> a= 15m/s²
