Answer:
<u>A kangaroo hops 60 m to the east in 5 s. What is the kangaroo's average velocity? ... The kangaroo stops at a lake for a drink of water and then starts hopping again to the south. Each second, the kangaroo's velocity increases 2.5 m/s.</u>
Answer:
Tբ = (C₁T₁ + C₂T₂)/(C₁ + C₂) = (C₁T₁)/(C₁ + C₂) + (C₂T₂)/(C₁ + C₂)
Explanation:
Let's Assume that T₁ > T₂, this means that, T₁ > Tբ > T₂
The zeroth law of thermodynamics explains that two bodies in thermal equilibrium will eventually end up with the same final body temperature.
Heat lost by body 1 = Heat gained by body 2
C₁ (T₁ - Tբ) = C₂ (Tբ - T₂)
C₁T₁ - C₁Tբ = C₂Tբ - C₂T₂
C₁Tբ + C₂Tբ = C₁T₁ + C₂T₂
Tբ(C₁ + C₂) = C₁T₁ + C₂T₂
Tբ = (C₁T₁ + C₂T₂)/(C₁ + C₂)
Tբ = (C₁T₁)/(C₁ + C₂) + (C₂T₂)/(C₁ + C₂)
x(2) = 30(2) = 60 m
y(2) = ½(-9.8)2² = -19.6 m
x(4) = 30(4) = 120 m
y(4) = ½(-9.8)4² = -78.4 m
x(6) = 30(6) = 180 m
y(6) = ½(-9.8)6² = -176.4 m
x(8) = 30(8) = 240 m
y(8) = ½(-9.8)8² = -313.6 m
x(10) = 30(10) = 300 m
y(10) = ½(-9.8)10² = -490 m
