Treat the collision as elastic. A moving billiard ball hits an identical (except for color) stationary ball. After the collision, the orange ball always goes off in the positive x-direction. The final speeds are v and V. Calculate the angle θ that the green ball goes off in. (θ should be positive.) V0 = the initial green body's speed = 6 m/s M = the mass of both balls = 6 kg φ = the incoming green ball's angle = 70o It's always a good idea to check your answer with the momentum-conservation and energy-conservation equations.
An object of mass 3M, moving in the +x direction at speed vo, breaks into two pieces of mass M and 2M as shown in the figure. V = ? 2M 3M If 0 = 68.0° and 02 = 21.0°, determine the final velocities vi and vz of the resulting pieces in terms of vo. M , = ? U2 =
A radioactive nucleus at rest decays into a second nucleus, an electron, and a neutrino. The electron and neutrino are emitted at right angles and have momenta of pe = 9.26×10−23 kg⋅m/s and pν = 5.98×10−23 kg⋅m/s , respectively. Determine the magnitude of the momentum of the second (recoiling) nucleus. Determine the angle between the momentum of the electron and the momentum of the second (recoiling) nucleus.
During a fireworks display, a 0.280-kg bottle rocket approaches the top of its trajectory and explodes into two pieces as in the figure. The first piece (Piece 1) has mass 0.180 kg and the second piece (Piece 2) has mass 0.100 kg. Immediately after the explosion, the first piece is observed traveling to the left at a speed of4.30 m/sand the second piece is observed traveling at an angleθ = 39.0°above the horizon at a speed of 17.0 m/s. Determine the components of the bottle rocket's velocity immediately before the explosion. Vxi = m/s Vyi = m/s
A grenade is initially at rest. Suddenly, it explodes into many different pieces. If you were to sum up the momentum of all the pieces (and gases), what would the result be? Pick the correct answer from the following options.
(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?

This amazing summer adventure is finally winding down with some pool. Unfortunately, this pool table is wonky and some of the balls are larger than the others! Anthony hits the cue ball (mass = 0.15 kg) and it moves at 5 m/s when it strikes head on into the number 3 ball (mass = 0.30 kg). After this inelastic collision, the cue ball moves off at 60 degrees relative to the +x axis and the number 3 ball moves off at -30 degrees relative to the +axis as shown. What were the speeds of the two balls after the collision?
