A large truck and a small compact car have a head-on collision. During the collision, the truck exerts a force on the car, and the car exerts a force on the truck. Which force has the larger magnitude, or are they the same? Does your answer depend on how fast each vehicle was moving before the collision? Why or why not?
Solution 30DQ Step 1 of 3: From newton’s laws of motion, force is given by F= ma Using a= dv dt dv F=m dt Where F is the force, m is the mass, t is time and v is speed . From above equation, we can say that; force is directly proportional on both mass and rate of change of speed. Step 2 of 3: In the given case, F Ts the force exerted by the truck on car and F iC the force exerted by the car on truck. By newton’s third law, the two vehicles experience a force of same magnitude but opposite in direction, F = -F =F T C
