Question

Example 2.3: Water is flowing in a stream
with velocity 5 km/hr in an easterly direction
relative to the shore. Speed of a boat is relative
to still water is 20 km/hr. If the boat enters the
stream heading North, with what velocity will
the boat actually travel?​

Answer 1

Answer:

Speed of a boat is relativ to still water is 20 km/hr. ... Magnitud of the resultant velocity is calculated as follows 5 km/hr B 20 km/hr R=V20 +5 = 425 = 20.61 km/hr The direction of the resultant velocity is = tan = tan (0.25) = 14°04' The velocity of the boat is 20.61 km/hr in direction 14°04' east of north. 21 Pomalu.
