3. A pendulum consists of a thin rod of length and mass m suspended from a pivot in the figure to the right. The bob is a cube of side L and mass M, attached to the rod so that the line of the rod extends through the center of the cube, from one corner to the diametrically opposite corner (dashed line).After impact at CP, ball B moves in the direction of the line joining the center of the two balls, as shown. This is because the force (impulse) delivered by ball A to ball B acts normal to the surface of ball B, assuming there is no friction between the balls (a good assumption since billiard balls are smooth). Two small metallic spheres, each of mass m = 0.20 g, are suspended as pendulums by light strings from a common point, as shown below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of θ = 5.00 with the vertical. If each string has length L = 30.0 cm, what is the ...

An object with mass m1 = 5.00 kg rests on a rough horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2 = 10.0 kg, as shown below. Starting from rest, m2 falls 1.00 meters in 0.55 seconds. Determine the coefﬁcient of kinetic friction between m1 and the table. The force on a mass m 0 from a mass M is given by F=(Gm 0 M/r 2)˙û. where û is the unit vector from m 0 to M. The next point is the principle of superposition. If a mass m 1 exerts a force F 1 on m 0 and a mass m 2 exerts a force F 2 on m 0, then the resultant force on m 0 is the (vector) sum , F 1 +F 2.

8. An object with a mass M = 250 g is at rest on a plane that makes an angle θ = 30º above the horizontal. The coefficient of kinetic friction between M and the plane is µ k = 0.100. Mass M is attached by a string to another mass, m = 200 g, which hangs freely. When mass m has fallen 30.0 cm, its speed is A) 83 cm/s B) 48 cm/s C) 160 cm/s D ... 13. A ball with a mass of 200 g is tied to a light string with a length of 2.4 m. The end of the string is tied to a hook, and the ball hangs motionless below the hook. Keeping the string taut, you move the ball back and up until it is a vertical distance of 1.25 m above its equilibrium point. You then release the ball from rest.If the ball impacts between two nodes, the racquet bend at the impact point will be concave; if it hits above or below the two nodes, the racquet bend at the impact point will be convex. The concavity or convexity can make a difference to spin in the folding mode (Figure 11b) (and it can add sidespin in the bending mode). A ball is struck by a racket at a point A which is 2 m above horizontal ground. Immediately after being struck, the ball has velocity (5i +8j) m/s, where i and j are unit vectors horizontally andvertically respectively.
