Answer:
Magnitude of avg velocity,
Given:
Constant speed of train, v = 79 km/h
Time taken in East direction, t = 27 min =
Angle,
Time taken in east of due North direction, t' = 29 min =
Time taken in west direction, t'' = 37 min =
Solution:
Now, the displacement, 's' in east direction is given by:
Displacement in east of due North for 29.0 min is given by:
Now, displacement in the west direction for 37 min:
Now, the overall displacement,
(a) Now, average velocity, is given:
Magnitude of avg velocity is given by:
(b) angle can be calculated as:
