When we jump out of a boat standing in water it moves

Why does a person tend to fall when he jumps out from a moving train and tries to stop immediately?

Mr. Verma (50kg) and Mr. Mathur (60kg) are sitting at the two extremes of a 4 m long boat (40 kg) standing still in water. To discuss a mechanics problem, they come to the middle of the boat. Neglecting frictioin with water how far does the boat move on the water during the process?

A child in danger of drowning in a river is being carried downstream by a current that flows uniformly at a speed of 2.5 km//h. The child is 0.6 km from shore and 0.8 km upstream of a boat landing when a rescue boat sets out. If the boat proceeds at its maximum speed of 20 km//h with respect to the water, what angle does the boat velocity v make with the shore? How long will it take boat to reach the child?

In Fig. a man stands on a boat floating in still water. The mass of the man and the boat is 60 kg and 120 kg , respectively. a. If the man walks to the front of the boat and stops. what is the separation between the boat and the pier now? b. If the man moves at a constant speed of 3 m//s relative to the boat, what is the total kinetic energy of the system (boat + man)? Compare this energy with the kinetic energy of the system if the boat was tied to the pier.

If a man jumps out from a boat, the boat moves backwards. Why?

We know that when a boat travels in water, its net velocity w.r.t. ground is the vector sum of two velocities. First is the velocity of boat itself in river and other is the velocity of water w.r.t. ground. Mathematically: vecv_(boat) = vecv_(boat,water) + vecv_(water) . Now given that velocity of water w.r.t. ground in a river is u. Width of the river is d. A boat starting from rest aims perpendicular to the river with an acceleration of a = 5t, where t is time. The boat starts from point (1,0) of the coordinate system as shown in figure. Assume SI units. Find time taken by him to across the river.

A boat moves relative to water with a velocity which is 'n' times the river flow a) If n lt 1 boat can not cross the river b) If n = 1 boat can not cross the river without drifting c) If n gt 1 boat can cross the river along shortest path d) Boat can cross the river what ever is the value of n excluding zero value
