Question

A small sphere with mass m = 0.1 kg, held by an inextensible and massless thread 2 m long, at its other end, in turn, attached to a fixed point on the ceiling, like a pendulum, is Resting. Another sphere is thrown horizontally, making a frontal collision with the first, inelastic with a coefficient of restitution equal to 0.25. Calculate the minimum speed of the sphere that is thrown so that, after the collision, the sphere hanging from the thread describes a complete circumference in the vertical plane and the thrown sphere falls vertically.

Answer #1

minimum speed required for complete rotation in vertical plane is irrespective of mass.

Given by V=√5gR

Where R=radius of circular rotational path

g=Acceleration due to gravity=9.8m/s^2

Answer-9.90 m/s

3.2 A sphere of mass m and with charge q, hanging on a
non-conducting thread of length l, rotates around the vertical
axis. The filament thereby forms an angle with the vertical axis.
Which is the rotational period of the ball and the tension force of
the thread when another resting charge q is in the suspension point
of the first charge?
Thank you so much the help!

pendulum of mass m= 0.8 kg and length l=1 m is hanging
from the ceiling. The massless string of the pendulum is attached
at point P. The bob of the pendulum is a uniform shell (very thin
hollow sphere) of radius r=0.4 m, and the length l of the pendulum
is measured from the center of the bob. A spring with spring
constant k= 7 N/m is attached to the bob (center). The spring is
relaxed when the bob is...
