A 1055-kg van, stopped at a traffic light, is hit directly in the rear by a 660-kg car traveling with a velocity of 2.00 m/s. As

sume that the transmission of the van is in neutral, the brakes are not being applied, and the collision is elastic. What is the final velocity of each vehicle

Answer:

<h3>0.77m/s</h3>

Explanation:

According to law of conservation of energy

m1u1 + m2 u2 = (m1+m2)v

m1 and m2 are the masses of the bodies

u1 and u2 are the initial velocities

v is the final velocity after collision

Substitute the given values into the formula

1055(0) + 660(2) = (1055+660)v

0+1320 = 1715v

v = 1320/1715

v = 0.77m/s

Hence the final velocity of each vehicle is 0.77m/s

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
