Answer:
Explanation:
Given that,
Efficiency of heat engine,
Temperature of hot source,
We need to find the temperature of cold sink i.e. . The efficiency of heat engine is given by :
So, the temperature of the cold sink is 256.2°C. Hence, this is the required solution.
Taking right movement to be positive means leftward movement is negative.
Hence we have a deceleration of
Using this 'suvat' equation
we can determine the initial velocity
Hence the initial velocity is 13.0 meters per seconds
Hence we have a deceleration of
