Amotorboat traveling 4 m/s, east encounters a current traveling 3.0 m/s, north. a) what is the resultant velocity of the motorboat? b) if the width of the river is 80 meters wide, then how much time does it take the boat to travel shore to shore? c) what distance downstream does the boat reach the opposite shore?

Explanation:

It is given that,

Velocity in East,

Velocity in North,

(a) The resultant velocity is given by :

(b) The width of the river is, d = 80 m

Let t is the time taken by the boat to travel shore to shore. So,

t = 16 seconds

(c) Let x is the distance covered by the boat to reach the opposite shore. So,

x = 48 meters

Hence, this is the required solution.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
