What will happen when the car hits the hay bale? Select all that apply.
A. The car will do work on the hay
The bales of hay are placed at the botto
bale and push the bale forward.
B. The car's kinetic energy will transfer to the hay bale.
C. The hay bale's potential energy will transfer to the car.
D. The hay bale will do work on the car and stop the car's motion.

a, c, d, e are all applying about success strategies.

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.
