Answer:
The time taken is 
Explanation:
From the question we are told that
The value of 
The the interior temperature is 
The external temperature is 
The required interior temperature is 
The newton cooling law is

=> 
Now integrate both sides we have

Since c is a constant lnC = c will also give a constant so
=>
=>
substituting value


Hence


=>

Answer:
0.61°
Explanation:
Since the box move at constant velocity, it means there is no acceleration then we can say it has a balanced force system.
Pulling force= resistance force
From the formula for pulling force,
F(x)= Fcos(θ)
= 425×cos(35.2)
=347N
The force exerted downward at an angle of 35.2° below the horizontal= Fsin(θ)= 425sin(35.2)
=425×0.567=245N
Resistance force= (325N+ 245N) (α)= 570N(α)
We can now equates the pulling force to resistance force
570 (α)= 347N
(α)= 347/570
= 0.61
