Two identical bullets are fired one by a light rifle and another by a heavy rifle with the same force. Which rifle will hurt the shoulder and why?

Text Solution

AI Generated Solution

To determine which rifle will hurt the shoulder more when firing identical bullets with the same force, we need to analyze the situation using the concepts of momentum and recoil. ### Step-by-Step Solution: 1. **Understanding the Forces**: Both rifles are firing identical bullets with the same force. According to Newton's Third Law, for every action, there is an equal and opposite reaction. This means that the force exerted on the bullet will also exert a force back on the rifle (recoil). 2. **Momentum Consideration**: The momentum of an object is given by the product of its mass and velocity (p = mv). When the bullet is fired, it gains momentum in the forward direction, and the rifle gains an equal amount of momentum in the opposite direction (backward). ...

    A stationary observer receives sound from two identical tuning forks, one of which approaches and the other one recedes with the same speed (much less than the speed of sound). The observer hears 2 beats/ sec. The oscillation frequency of each tuning fork is v_(0)=1400 Hz and the velocity of sound in air is 350 m/s. The speed of each tuning fork is close to :

    Two identical discs of mass m and of radius R touch each other and move with the same velocity perpendicularly to the line segment which joins their centres of mass, along the surface of a horizontal smooth tabletop. There is a third disc of mass M and of radius R at rest, at a point on thhe perpendicular bisector of of the line segment joining the centres of mass of the two moving discs as shown in the figure. The two moving discs collide elastically with the third one, which is at rest there is no friction between the rims of the discs. What should the ratio of M/m be in order that after the collision the two discs of mass m move perpendicularly to their intial velocity?
