acar is travelling at 72km/ hr and when the breaks are applied it experiences a uniform retordation 2m/sec how long does it take the car to stop and how far does it travel from the instant the breaks are applied

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

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.
