Assuming that the object doesn't rest, and keeps that pace going for three days straight, first you need to calculate the the amount of meters the object can travel in one day. And to find that out you need to find the number of meters it travels per minute, which is 5 times 60, which is 300. Then calculate how far it travels per hour, which is 300 times 60, which is 18,000. Then find out how far it travels in a day, which is 18,000 times 24, which is 432,000. Then to find how many meters it travels in 3 days you multiply 432,000 by 3 which is 1,296,000. Then to find how many kilometers that is, you divide that by 1,000, which comes out to be 1296 kilometers in 3 days.

Answer from: Quest

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 -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [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.
