Question

VM= 32Km/h, ∆S=?, ∆T=7s

me ajudem pelo amor de Deus.

Answer 1

Vsmos calcular com a formula de velocidade media :
dados :
>>>>>>>
Vm = 32km/h
At = 7seg.
As = ???

1ero vamos transformar km/h para m^s

Vm = 32 x 3,6m/s
Vm = 115,20 m/s

2do vamos a calcular com a formula de velocidade media encontraremos As :

Vm = As
.........___
...........At

115,20 m/s = As
........................___
.........................7s

As = 115,20 m/s x 7s
As = 806,40 m
