PHYSICS KINEMATICS Question # 50 From HC Verma Physics:Kinematics Chapter 2
Two friends A and B are standing at a distance x apart from each other and wind is blowing from A to B. A beats a drum and B hears the sound after time t₁ after he sees the event. Now A and B interchange their position and the experiment is repeated. This time B hears the drum after time t₂ after seeing the event. Find the velocity of sound in still air and the velocity of wind.

Question # 46 From HC Verma Physics: Kinematics Chapter 2
A river 400 m wide is flowing at a rate of 2.0 m/s. A boat is sailing at a velocity 10m/s with respect to the water in a direction perpendicular to the river.

Find the time taken by the boat to reach the opposite bank.
How far from the point directly opposite to the starting point does the boat reach the opposite bank?

SOLUTION

Question # 48 From HC Verma Physics: Kinematics Chapter 2
A swimmer wishes to cross a 500 m wide river flowing at 5Km/hr. His speed with respect to water is 3Km/hr. The man has to reach the other shore at a point directly opposite to his starting point. If he reaches the other shore somewhere else, he has to walk down to this point. Find the minimum distance that he has to walk.
