That's the period of time known as one solar "day". We subdivide it into 24 slices which we call "hours". Using this system of time units, the day is about 4 minutes longer than one complete axial rotation of the Earth.
It grows every time it needs to grow for the population of the environment
A. Without doing much math, it can be seen from the graph that the altitude is decreasing. The slope of the position time graph determines velocity, so by comparing the start to the end of the graph, it can be seen that -100m was the change in altitude and 25 seconds was the change in time. Divide -100 by 25 to get -4m/s.

Determine the average acceleration during each time interval. c. ... the ground with a an initial velocity of 169 m/s at an angle of 23.0 O above the horizontal; a. ... A 4.00 kg mass is sitting at rest on a horizontal surface.
Explanation:
Answer:
8 km/hr
Explanation:
Convert minutes to hours:
30 min × (1 hr / 60 min) = 0.5 hr
Average speed is distance over time:
v = (4 km) / (0.5 hr)
v = 8 km/hr
