Suppose you start at washington, d. c. (39 n, 77 w), and travel 600 mi due south, then 600 mi due west, then 600 mi due north, and then 600 mi due east. where will you arrive with respect to your starting point?

I will end up at the same place I started

Explanation:

On a map if I travel 600 mi due south from Washington D.C. it will be a straight line down. After that the west direction will be a straight line towards the left which will be 600 mi. Then going north from this point will be straight line upwards which will be 600 mi. Then going east will be a straight line towards the right for 600 mi reaching the point of origin.

Hence, I will reach Washington D.C.

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

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
