Answer:
(a) check attachment
(b)5 m/s²
Explanation:
Given: radius = 2.00mm: density = 2500kg/m³: viscosity of glycerin = 1.5pa: decity of glycerin = 1250kg/m³: g = 10N/kg = 10m/s²: Fdrag = 6πnrv
(a) for answer check attachment.
(b) For the magnitude of the balls initial acceleration:
Initial net force(f) = mg - upthrust
=
acceleration (a) =
c.) fromthe force diagram in the attachment; when the ball attains terminal velocity the net force will be zero(0)
d.) For the magnitude of terminal velocity:
e.) when the ball reaches terminal velocity, the acceleration is zero (0)
