Answer:
The car's instant speed is 20m/s
Explanation:
a = at + an
The above equation is a vector equation
a is the resultant acceleration
at is the tangent acceleration
an is the normal acceleration

Answer:
Detailed solution is given below:
Answer:
Given:
P₁ = 500 kPa
T₁ = 860 K
P₂= 100 kPa
T₂ = 460 K
Let's take entropy properties of T1 and T2 from ideal properties of air,
at T = 860K, s(T₁) = 2.79783 kJ/kg.K
at T = 460K, s(T₂) = 2.13407 kJ/kg.K
using entropy balance equation:
= - 0.2018 kJ/kg. K
In this case the entropy is negative, which means the value of exit temperature is not correct, beacause entropy should always be positive(>0).
