A particle of mass m (particle #1) is fired head-on at speed 48 m/s toward another particle of mass 3m (particle #2) which is at rest.  The result of this collision is that #1 comes to a complete stop, and #2 moves forward.  (a) At what speed does particle #2 emerge from the collision?  (b) What fraction of the original kinetic energy is lost during this process?

During the collision between the ball and the racket, the velocity vector of the tennis ball is exactly reversed such that its speed is the same before and after the collision. Determine the speed of the ball assuming its mass to be 150 g. A nucleus A of mass 2 m moving with velocity 100 m/s collides inelastically with a stationary nucleus B of mass 10 m. After collision, the nucleus A travels at 90oto the original incident direction while B proceeds at an angle 37oto the original incident direction. a) Find the speeds of A and B after the collision.b) What fraction of the initial kinetic energy is gained or lost due to the collision? Two blocks having equal masses m1 = m2 = 10 kg are placed in contact on a surface inclined at an angle of 40ofrom the horizontal as shown in the figure below. The coefficient of static friction between the incline and the lower block is µs1 = 0.90 and the coefficient of kinetic friction is µk1 = 0.40.

As shown in the figure below, a bullet is fired at and passes through a piece of target paper suspended by a massless string. The bullet has a mass m, a speed v before the collision with the target, and a speed  (0.516)v  after passing through the target. The collision is inelastic and during the collision, the amount of kinetic energy lost by the bullet and paper is equal to [(0.333)Kb BC] , that is, 0.333 of the kinetic energy of the bullet before the collision. Determine the mass M of the target and the speed V of the target the instant after the collision in terms of the mass m of the bullet and speed v of the bullet before the collision. (Express your answers to at least 3 decimals.) V =____v M = ___m
