Joe and Jim start at rest at the starting line of a race track. Both runners accelerate at the same rate, but Joe accelerates fo
eduard

Answer:

Vf₂ = 2 Vf₁

It shows that final speed of Joe is twice the final speed of Jim.

Explanation:

First, we analyze the final speed of Jim by using first equation of motion:

Vf₁ = Vi + at

where,

Vf₁ = final speed of Jim

Vi = initial speed of Jim = 0 m/s

a = acceleration of Jim

t = time of acceleration for Jim

Therefore,

Vf₁ = at   ---------------- equation (1)

Now, we see the final speed of Joe. For Joe the parameters will become:

Vf = Vf₂

Vi = 0 m/s

a = a

t = 2t

Therefore,

Vf₂ = 2at  

using equation (1):

<u>Vf₂ = 2 Vf₁</u>

<u>It shows that final speed of Joe is twice the final speed of Jim.</u>

Qual a massa de água a 45 °C que devemos misturar com 200 g de água a 15 °C, para que o sistema entre em equilíbrio térmico a 35
Stells [14]

Responda:

400 g

Explicação:

Dado o seguinte:

Deixe Mass (m1) = m em t1 = 45 ° C

Massa (m2) = 200g em t2 = 15 ° C

Equilíbrio térmico (T) = 35 ° C

Usando a relação:

m1 * C * ΔT = m2 * C * ΔT

Onde m1 e m2 são as massas; C = capacidade de calor específico da água e ΔT é a mudança de temperatura

m1 * ΔT = m2 * ΔT

m * (45 ° C - 35 ° C) = 200 * (35 ° C - 15 ° C)

10 * m = 200 * 20

10 * m = 4000

m = 4000/10

m = 400g
