A 4.86-g bullet is moving horizontally with a velocity of +366 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1223 g, and its velocity is +0.662 m/s after the bullet passes through it. The mass of the second block is 1605 g. (a) What is the velocity of the second block after the bullet imbeds itself?

A 180-g billiard ball is shot toward an identical ball at velocity  vi = 6.90 m/s.  The identical ball is initially at rest. After the balls hit, one of them travels with velocity  v1, f = (1.80 + 2.22) m/s.  What is the velocity of the second ball after the impact? Ignore effects of friction during this process. (Express your answer in vector form.) v2, f =         m/s

An unstable atomic nucleus of mass 1.62 x 1026 kg initially at rest disintegrates into three particles. One of the particles, of mass 5.06 x 1027 kg, moves in the y direction with a speed of 6.00 x 10 m/s. Another particle, of mass 8.50 x 1027 kg, moves in the x direction with a speed of 4.00 x 10 m/s. (a) Find the velocity of the third particle. m/s (b) Find the total kinetic energy increase in the process.

A 5.37-g bullet is moving horizontally with a velocity of + 346 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1179 g, and its velocity is + 0.556 m/s after the bullet passes through it. The mass of the second block is 1581 g. (a) What is the velocity of the second block after the bullet imbeds itself? (b) Find the ratio of the total kinetic energy after the collision to that before the collision.

In the figure below, particle 1 of mass m, = 0.21 kg slides rightward along an x axis on a frictionless floor with a speed of 2.4 m/s. When it reaches x = 0, it undergoes a one-dimensional elastic collision with stationary particle 2 of mass m2 = 0.40 kg. When particle 2 then reaches a wall at xw = 70 cm, bounces from it with no loss of speed. At what position on the x axis does particle 2 the collide with particle 1? cm 02 x (cm)

Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 7.24 m/s and scatters at an angle of 30° with respect to its incoming direction. What is the velocity (magnitude in m/s and direction in degrees counterclockwise from the +x-axis) of puck 1 after the collision? (Assume the +x-axis is to the right.) 30° magnitude m/s direction o counterclockwise from the +x-axis

Hockey puck A slides along a sheet of frictionless ice, moving due east with speed 2.80 m/s. It then collides with hockey puck B, which is initially at rest. After the collision, puck A is moving in a direction 30.0° north of east with a speed of 2.10 m/s. The masses of the hockey pucks are ma = 1.20 kg and mB = 1.40 kg. Apply conservation of linear momentum to the puck A+B system to find the final speed (in units of m/s) and direction of travel (in units of degrees) of puck B. 2.10 m/s 2.80 m/s A 30.0° before after collision collision

(ODC-1) Consider two hockey pucks, each with mass 1.25 kg, on frictionless ice. Puck A is initially moving due east at 2.35 m/s towards puck B, which is initially stationary. The pucks. collide head on. After the collision, puck B moves east with a speed of 1.45 m/s. (a) What is puck A's speed (in m/s) after collision? What direction is it moving in? (b) How much kinetic energy (in Joules) is lost from the system during the collision? (c) If the collision were completely elastic, what wold the final speed and direction of each puck be?
