A motorboat whose speed in still water is 18 km/h, takes 1 hour more to go 24 km upstream than to return downstream to the same spot. Find the speed of the stream. Find the speed of the stream. View Solution
A motorboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. The speed of the stream (in km/hr) is: View Solution
A motorboat whose speed in still water is 18 km/h, takes 1 hour more to go 24 km upstream than to return downstream to the same spot. Find the speed of the stream. Find the speed of the stream. View Solution
A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 m s − 2 for 8.0 s. How far does the boat travel during this time? How far does the boat travel during this time?
A motor boat whose speed in still water is 18 km /hr, takes 1 hour more to go 24 km upstream than to return to the same spot.
A motorboat goes downstream in river and covers a distance between two coastal towns in 6 hours. It covers this distance upstream in 8 hours. If the speed of the stream is 2 km/hr, find the speed of the boat in still water. [4 MARKS]
A motorboat of mass m moves along a lake with velocity v 0. At the moment t = 0 the engine of the boat is shut down. Assuming the resistance of water to be proportional to the velocity of the boat → F = − r → v, find the velocity of the motorboat as a function of the distance covered with the engine shutdown.
From a motorboat moving downstream with a velocity 2 m / s with respect to river, a stone is thrown. The stone falls on an ordinary boat at the instant when the motorboat collides with the ordinary boat. The velocity of the ordinary boat with respect to the river is equal to zero. The river flow velocity is given to be 1 m / s. The initial ...
36.Motorboat covers the distance between two spots on the river in 8h and 12h downstream and upstreeam resp. the time required by the boat to cover this distance i still water is: View Solution A motot boat covers the distance between two spots on the river banks in t_1=8h and t_2=12h in down stream and upstream respectively.
A motorboat going downstream overcame a raft at a point A. One hour later it turned back and after sometime passed the raft at a distance 12 km from the point A. Find the river velocity (in km/hr) assuming the speed of the motorboat to be constant.
