A student jogs around a park two times, starting and ending at the gate to the park. The jogging track is a square, with 40 m on each side. Which of the following statements is
true about the student’s distance and displacement?
a. The distance is 320 m, and displacement is 160m.
b. The distance is 160m, and the displacement is 40 m.
c. The distance is 320m, and the displacement is 320 m.
d. The distance is 320 m, and the displacement is 0

this is poiselle's equation from fluid mechanic in physics. mech eng

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.
