A hiker walks 8.86 m, N and 11.81 m, E. What is the magnitude of his resultant displacement?

14.764 (rounded to the nearest thousandths)

Explanation:

Reminder: displacement is the length of the shortest line you can draw from the original point to your current point.

In this case, we can use the pythagorean theorem, where c is the displacement:

8.86^2+11.81^2=c^2

217.9757=c^2

c≈14.764 (rounded to the nearest thousandths)

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.
