A cannon and a supply of cannon balls are inside a sealed rail road car. The cannon fires to the right, the car recoils to the left. The canon balls remain in the car after hitting the far wall. Show that no matter how the cannon balls are fired, the rail road car cannot travel more than L. assuming it starts from rest.

Two 20 kg cannon balls are chained together and fired horizontally with a velocity of 200 m/s from the top of a 30 m wall. The chain breaks during the flight of the cannon balls and one of them strikes the ground at t = 2 s, at a distance of 250 m from the foot for the wall, and 5 m to the right of line of fire determine the position of the other cannon ball at that instant Neglect the resistance of air.

A `30 kg` projectile moving horizontally with a velocity `vecv_(0) = ( 120 m//s ) hati` explodes into two fragments `A` and `B` of masses `12 kg` and `8 kg`, respectively. Taking point of explosion as origin and knowing that `3s` later position of fragment a is (`300 m, 24 m, -48 m`), determine the position of fragment `B` at the instant.

Figure shows the system is at rest initially with x = 0, A man and a woman both are initially at the extreme carrier of the platform. The man and the woman start to move towards each other. Obtain an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform. `

A cart of mass `M` is at rest on a frictionless horizontal surface and a pendulum bob of mass `m` hangs from the roof of the cart. The string breaks, the bob falls on the floor, makes several collisions on the floor and finally lands up in a small slot made on the floor. The horizontal distance between the string and the slot is `L`. Find the displacement of the cart during this process.

Mr. Verma (50 kg) and Mr. Mathur (60 kg) 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 friction with water how far does the boat move on the water during the process?
