Explanation:
Answer:
C. Friction between the box and the floor is 25N to the left
Explanation:
Answer:
85.556metres
Explanation:
Using pythagorean theorem
C²=A²+B²
we have c as the hypotenuse vector A thus:
93.8²=A²+38.4²
93.8²-38.4²=A²
8794.44-1474.56=A²
7319.88=A²
A=85.556

From the question we are told that:
Speed of Train 
Angle 
Height of window 
Width of window 
The Horizontal distance between B and A from Trigonometric Laws is mathematically given by


Therefore
Distance from A-A


Therefore
Time Required to travel trough d is mathematically given as
