Answer:
i think maybe because it has more than 6 or 5 parts.
Since the mass is moving in a horizontal circle, we do not look at gravity, tension in string or weight of the mass.
<em>
Time period for one cycle around circle = T = 0.42 seconds</em>
<em>Tangential Velocity or speed of the mass = </em>
<em> tangential distance traveled in 1 cycle or revolution / time period</em>
= circumference of circle / time period
<em> = 2 π radius / T = 2 π 1 meter / 0.42 sec </em>
<em> = 14.96 m/s</em>
The stone tool industry being described is the Acheulean. These tools are characterized by hand axes and bifacial blades and were made by many different species of Homos, including Homo erectus and early Homo sapiens.
