    1. The problem statement, all variables and given/known data

    Question 1.A table exerts a 4.0 newton force on a book which lies at rest on its top. The force exerted by the book on the table is. Question 2. A bullet with mass 0.40kg is fired with an initial velocity of 400m/s from a gun with mass 5.0kg. The speed of the recoil of thegun is Question 3. An automobile of mass 1.46 e3 rounds a curve of radius 25.0 m with a velocity of 15.0m/s the centripetal force exerted on the automoblie while rounding the curve is Question 4. What Net Force is necessary to give a 4.0 kg mass initially at rest an acceleration of 5.0m/s^2 Question 5. A 2.0 kg mass is moving to the right at 3.0m/s An 4.0 kg mass is moving to the left at 2.0 if after collision the two masses join together what is their velocity after collision? Is this inelastic or elastic? Question 6. A 5n force directed to the west acts on an object for 2.0 seconds. What is the change in momentum of the object?Question 7. An object travels in a circular path of radius 5.0 meters at uniform speed of 5. m/s What is the magnitude of the object's acceleration? Question 8. A table exerts a 10 Newton force on a book which lies at redt on its top. The force exerted by the book on the table is Question 9. An object traveling at 5.0m/s East has a mass of 6.0 kg. What is the magnitude of the object's momentum? Question 10. An object with a mass of 10.0kg is accelerated at 5.0m/s/s. The net force acting on the mass is
