A 0.18 kilogram billiard ball whose radius is 3.3 centimeter is given a sharp blow by a cue stick. The applied force is horizontal and the line of action of the force passes through the center of the ball. The speed of the ball just after the blow is 4.1 m/s and the coefficient of kinetic friction between the ball and the billiard table is 0.59.
(a) Obtain how long does the ball slide before it begins to roll without slipping?
s
(b) Determine how far does it slide?
m
(c) Calculate what is its speed once it begins rolling without slipping?
m/s
An unstrained horizontal spring has a length of 0.34 m and a spring constant of 290 N/m. Two small charged objects are attached to this spring, one at each end. The charges on the objects have equal magnitudes.
A spring is hung from a ceiling, and an object attached to itslower end stretches the spring by a distance of 5.00 cm from its unstretched position when the system is in equilibrium. determine the mass of the object
