Explanation:

If you place two of the same experiments on a scale, and cover one with a cup, the one with the cup will "lose" mass, while the other won't, due to the cup being a "containment field" I guess you could call it.

A horse runs 1 km in 15 s. What is the average speed
Reptile [31]

The average speed of the horse for the entire motion is 66.67 m/s.

The given parameters;

  • <em>distance traveled by the horse, d = 1 km = 1,000 m</em>
  • <em>time of motion of the horse, t = 15 s</em>

The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.

The average speed of the horse is calculated as follows;

average\ speed = \frac{distance}{time} \\\\average\ speed =  \frac{1000 \ m}{15 \ s} = 66.67 \ m/s

Thus, the average speed of the horse for the entire motion is 66.67 m/s.
