do u have a photo that comes w/ this? so i could help more :) ?
Explanation:
Answer:F=0.0882kg
Explanation:
The period it takes to make one revolution is 1.5 seconds / revolutions,
v = r * (change in angle / change in time)
the change in angle is 2pi, for one whole revolution. the time is 1.5 second per revolution, and the radius is 0.1.
v = (2 * pi * 0.1 cm * / 1.5second
v = 0.42m/s
a=v^2/r
a=0.42^2 /0.1 =1.764m/s2
F=ma
F=0.05*1.764
F=0.0882kg
The answer is c, because ball is falling so its gravitationl potential energy decreases, but it kinetic energy increases. Energy is always conserved.
