Alocomotive is pulling an empty freight car with a constant acceleration on a horizontal surface. the mass
of the locomotive is five times the mass of the car. which statement is true about the force applied by the
car on the locomotive?
a. 5 times greater than the force of the locomotive on the car.
b. 5 times less than the force of the locomotive on the car.
c. equal to the force of the locomotive on the car.
d. opposite in direction to the force of the locomotive on the car.
e. the same direction as the force of the locomotive on the car.

i know the answers are c and d can someone explain why

i'm on my way to history not a mistory.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
