Aremote controlled car travels 15 m north, back tracks 5 meters and stops.   what is the car’s displacement?

The displacement is the change in position, or a displacement is a vector whose length is the shortest distance from the initial to the final position.

Therefore,

Displacement = final position - initial position.

Given,  final position = 15 m and initial position = 5 m

So,

Displacement = 15 m - 5 m = 10 m

Thus, the car’s displacement is 10 m

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
