Question
Please answer the following questions and show your work.Q8,3 A kg rifle fires a 000500-kg bullet at a speed of 300 m/s. Which force is greater in magnitude: the force that the rifle exerts on the bullet or the force that the bullet exerts on the rifle? A The force that the rifle exerts on the bullet is greater. B,The force that the bullet exerts on the rifle is greater. C. Both forces have the same magnitude. D, The answer depends on how the rifle is held. E. The answer depends on how the rifle is held and on the inner workings of the rifle.
Explanation / Answer
both force have same magnitude due ot Newton's third law
according to Newton third law, every action there is and equivalent and opposite reaction. so both forces have same magnitude but in opposite direction
option (C) is correct answer
-------------------------------------------------------------
car 1= m ( 50 mi/h)
kinetic energy of car 1 = /12 * m ( 50 mi/h)^2
Car 2 = 1/2 m( 50 mi/h)^2
momentum of car 2 = m ( 50 mi/h)
both car 1 and 2 have same momentum and kinetic energy
option(D) is correct answer
