Explanation:
From the question we are told that
The coefficient of static friction is 
The initial speed of the train is 
For the crate not to slide the friction force must be equal to the force acting on the train i.e

The negative sign shows that the two forces are acting in opposite direction
=> 
=> 
=> 
=> 
From equation of motion

Here v = 0 m/s since it came to a stop
=> 
=> 
=> 
Explanation:
Power output of the bulb:
0.021 × 60 W = 1.26 W
Energy produced by the bulb in 1 second:
E = Pt
E = (1.26 W) (1 s)
E = 1.26 J
Round as needed.
