Question

A) S = 10 + 6.t + 3.t 2 t =1s

B) S = 20 + 4.t + 4.t 2 t = 3s

C) S = 15 + 3.t + 2.t 2 t = 4s

Answer 1

Resposta:

a) 19 m

b) 68 m

c) 59 m

Explicação:

a) s = 10 + 6•1 + 3•1^2

s = 10 + 6 +3•1

s = 19 m

b) s = 20 + 4•3 + 4•3^2

s = 20 + 12 + 4•9

s = 32 + 36

s = 68 m

c) s = 15 + 3•4 + 2•4^2

s = 15 + 12 + 2•16

s= 27 + 32

s = 59 m
