A 2 kg- 200 mm diameter Ball A is rolling in the floor with a constant speed of 10 m/s when a 0.5 kg- 120 mm diameter ball B flying 200 mm above the floor (to the center of ball B) with a constant speed of 45 m/s hit it. Assume e= 0.85 for both balls and e= 0.5 for the floor and ball A. Find the distance between the balls when ball B hits the floor for the first time. The coef. of friction between the ball and the floor is 0.2

A puck of mass m₂ = 72.0 g and radius r₁ = 3.70 cm glides across an air table at a speed of = 1.50 m/s as shown in Figure a. It makes a glancing collision with a second puck of radius r₂ = 6.00 cm and mass m₂ = 105 g (initially at rest) such that their rims just touch. Because their rims are coated with instant-acting glue, the pucks stick together and rotate after the collision (Figure b). m₁ m₂ b (a) What is the magnitude of the angular momentum of the system relative to the center of mass? kg. m²/s (b) What is the angular speed about the center of mass? rad/s
(COLLAB Gauss's Law for Mass) Journey through the Center of the Earth. A 1024-kg blue ball is dropped from an initial z-position of 4.2 x 106 m through the center of a planet with radius 7.3 x 106 m. If the mass of the planet is 33.4 x 1015 kg, measure the displacement of the ball at time t = 9 s?
In the figure, two satellites, A and B, both of mass m = 49.1 kg, move in the same circular orbit of radius r = 7410 km around Earth (mass ME = 5.98×1024 kg) but in opposite senses of rotation and therefore on a collision course. (a) Find the total mechanical energy EA+ EB of the two satellites + Earth system before the collision. (b) If the collision is completely inelastic so that the wreckage remains as one piece of tangled material (mass = 2m), find the total mechanical energy immediately after the collision. (c) Just after the collision, is the wreckage falling directly toward Earth’s center or orbiting around Earth?

A rod of mass M = 3.45 kg and length L can rotate about a hinge at its left end and is initially at rest. A putty ball of mass m = 55 g, moving with speed v = 4.3 m/s, strikes the rod at angle θ = 63° from the normal at a distance D = 2/3 L, where L = 1.05 m, from the point of rotation and sticks to the rod after the collision. Part (a) What is the initial angular momentum of the ball, in kilogram meters squared per second, right before the collision relative to the pivot point of the rod? Part (b) What is the total moment of inertia If with respect to the hinge, of the rod-ball-system after the collision, in terms of the variables from the problem statement? Part (c) What is the angular speed ωf of the system immediately after the collision, in radians per second?

A binary-star system contains a visible star and a black hole moving around their center of mass in circular orbits with radii r1 and r2 , respectively. The visible star has an orbital speed of v=5.36x105 ms-1 and a mass of m1 =5Ms ,where Ms= 1.98x1030kg is the mass of our Sun. Moreover, the orbital period of the visible star is T = 30 hours.(a) What is the radius r1 of the orbit of the visible star?(b) Calculate the mass m2 of the black hole in terms of MS . [Hint: One root of the equation x3 = 20a(5a+x)2 , where a is a constant, is x = 28a .]
A 4-Kilogram object slides, on a smooth surface, towards the north at a velocity of 5 meters per second. The object hits a fixed pole and is deflected from north to east by an angle of 60° and has a velocity of 5 meters per second. The change in the magnitude of the northward component of the moment of the object is
An asteroid with a mass of 75 kg is travelling in deep space, far away from the the gravitational pull of any large body. It is moving at a speed of uA = 5.0 ms-1, in the positive x direction towards another smaller asteroid B which has a mass of 65 kg - which is stationary. Following the collision the asteroids move at 54° to each other and both at 27° to the original direction with speeds vA and vB. Neither asteroid is spinning prior to or following the collision. By considering conservation of momentum, what are the speeds vA and vB following the collision?
An instrument-carrying projectile of mass m1 accidentally explodes at the top of its trajectory. The horizontal distance between launch point and the explosion is x0. The projectile breaks into two pieces that fly apart horizontally. The larger piece, m3, has three times the mass of the smaller piece, m2. To the surprise of the scientist in charge, the smaller piece returns to earth at the launching station. Neglect air resistance and effects due to the earth’s curvature. How far away from the original launching point does the larger piece land
