- Use Newton's Laws to explain questions 1 and 2. 1. A car is driving on an icy road It tries to turn around a curve but continues in a straight line and ends up in the ditch. 12 2. Many people are familiar with the fact that a rifle recoils when fired. A gunpowder explosion creates hot gases that expand outward allowing the rifle to push forward on the bullet. Consistent with Newton's third law of motion the bullet pushes backwards upon the rifle. Choose which statement is correct and explain your answer.12 The force acting on the recoiling rifle is: a. Greater than that acting on the bullet. b. Smaller than that acting on the bullet. c. The same as that acting on the bullet.
