A bar of mass mb is to be released from rest at the position shown. Three possible designs use rollers differently. All rollers have the same identical masses m, and radii r. Each can be approximated as cylinders. After dropping a distance h, which would move the fastest, and which the slowest. Quantify your answer with an equation of v for each case. The designs will be made to allow no slipping and make any bracket weight negligible. HH Q Search A B (a) A THE B (b) O O |-----| O A al p BCD ESP |--| x O
A bowling ball ( m₁ = 3.00 kg and radius of r = 50.0 mm) which has an angular and linear velocity of 57.1 rad/s and 2.85 m/s, respectively, rolls without sliding and hits a slender Bar B of mass m_2 = 1.00 kg and length L = 0.12 m, which is initially at rest as shown in the following figure. Neglecting the friction between the sphere and the bar, and knowing the coefficient of restitution between the sphere and the bar is 0.2, determine (1) the angular velocity of Bar B immediately after impact, and (2) the linear velocities of sphere A and bar B immediately after impact (and at their centroids).

QUESTION: A bowling ball ( m₁ = 3.00 kg and radius of r = 50.0 mm) which has an angular and linear velocity of 57.1 rad/s and 2.85 m/s, respectively, rolls without sliding and hits a slender Bar B of mass m_2 = 1.00 kg and length L = 0.12 m, which is initially at rest as shown in the following figure. Neglecting the friction between the sphere and the bar, and knowing the coefficient of restitution between the sphere and the bar is 0.2, determine (1) the angular velocity of Sphere A and Bar B immediately after impact, and (2) the linear velocities of sphere A and bar B immediately after impact (and at their centroids). ANSWER: Answers I got are: (they are wrong :< need help) Angular velocity of Sphere A immediately after impact: -/+ 3.34 rad/s (both are wrong) Angular velocity of Bar B immediately after impact: 8.09 rad/s The linear velocity of sphere A immediately after impact (and at the centroid) : 0.16 rad/s2 or 0.485 rad/s2 (both wrong) The linear velocity of Bar B…
The mass center, G, of the 2-lb ball has a velocity of (vd - 5 ft/s when it strikes the end of the smooth 4-lb slender bar, which is at rest. The bar has a length l-Sft. The coefficient of restitution is e-0.8. The goal is to find the angular velocity of the bar after impact. Steo 5: Finally find the angular velocity of the bar after impact in rad/s.

A thin, light string is wrappedaround the outer rim of a uniform hollowcylinder of mass 4.75 kg having innerand outer radii as shown in Fig..The cylinder is then released from rest.(a) How far must the cylinder fall beforeits center is moving at 6.66 m/s? (b) Ifyou just dropped this cylinder withoutany string, how fast would its center bemoving when it had fallen the distancein part (a)? (c) Why do you get twodifferentanswers when the cylinderfalls the same distance in both cases?
EXAMPLE 4 A solid ball with a mass m is thrown on the ground such that at the instant of contact it has an angular velocity and velocity components (VG) and (VG) as shown. If the ground is rough so no slipping occurs, determine the components of the velocity of its mass center just after impact. The coefficient of restitution is e. (va)yt (va)a
9. 2) The target is a thin 4.3-kg circular disk of radius r= 273 mm that can rotate freely about the z axis. Initially it is at rest. A 21-g bullet, traveling at v = 630 m/s, strikes the target at A and becomes embedded in it. The dimensions are di = 219 mm and d2 = 90 mm. If the impact time is 0.02 s, determine the average impact force between the bullet and the target. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s?. 'pe
