A ball of mass M = 1.40 kg and radius r = 4.70 cm is attached to one end of a thin, cylindrical rod of length L = 12.0 cm and mass m = 0.880 kg. The ball and rod, initially at rest in a vertical position and free to rotate around the axis shown in the figure below, are nudged into motion. M m (a) What is the rotational kinetic energy of the system when the ball and rod...

PROBLEM 17.113 The slender rod AB of length L = 1 m forms an angle B = 30° with the vertical as it strikes the frictionless surface shown with a vertical velocity 7 = 2 m/s and no angular velocity. Knowing that the coefficient of restitution between the rod and the ground is e = 0.8, determine the angular velocity of the rod immediately after the impact.

2. (40 points) A soccer ball tester consists of a 15-kg slender rod AB with a 1.1-kg sim- ulated foot located at A and a torsional spring located at pin B. The torsional spring has a spring constant of k 910 N.m/rad and is unstretched when AB is its lowest position. Fig. 2 depicts the simulation. The length of AB is 0.9 m, and you can assume that the foot ban be modcled as a particle, Knowing that the velocity...

a. The mass of a golf ball is .046 kg; the mass of a club head is .28 kg; and, the velocity of the club head is 55 m/s before it impacts the ball. If the coefficient of restitution of the ball is .82, how fast is the ball moving after impact? (1pt) Use this formula for part a.: v1 = ((CoR + 1)m2u2 + u1(m1 – CoRm2)) / m1 + m2 Where v = velocity after...
