- A proton of mass m undergoes a head on collision with a stationary atom of mass 13m. If the initial speed of the proton is 455 m/s, find the speed of the proton after the collision.For Christmas you receive a new toy train engine of mass m1 = 1.0 kg. Playing around, youset your new toy going at 2.0 m/s, but you inadvertently cause a crash with another train of massm2 = 1.0 kg initially at rest. The crash converts 800 mJ of kinetic energy into sound and thermalenergy. What are the resulting velocities of the two trains after the collision?Two marbles of the same mass perform a perfectly clastic and one-dimensional collision. If one of them is at rest, and the other has a speed of 4 m/s before the collision, determine the speeds after the collision.
- A 480-kg car moving at 16.4 m/s hits from behind a 570-kg car movingat 13.3 m/s in the same direction. If the new speed of the heavier car is 14.0 m/s,(a) what is the speed of the lighter car after the collision, assuming that anyunbalanced forces on the system are negligibly small, and(b) what average power is dissipated during the collision if they collide for 1.4seconds?A proton of mass m undergoes a head on collision with a stationary atom of mass 13m. If the initial speed of the proton is 350 m/s, find the speed of the proton after the collision.A 2.64 -g bullet moving at 280 m/s enters and stops in an initially stationary 2.10−kg wooden block on a horizontal frictionless surface.

- A 29-g rifle bullet traveling 190 m/s embeds itself in a 3.6-kg pendulum hanging on a 2.7-m- long string, which makes the pendulum swing upward in an arc. (a) Calculate velocity of block plus bullet after collision. (b) Determine the vertical height, h of the pendulum's maximum displacement. m M VM = 0 M+ m (a) (b)A billiard ball moving at 5.20 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.67 m/s at an angle of 26.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude direction 1.56 × Check the initial and final kinetic energies. You will find that your final kinetic energy is not equal to the initial kinetic energy. m/s ° (with respect to the original line of motion)In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0235 kg and the mass of the pendulum is 0.250 kg, how high ℎ will the pendulum swing if the marble has an initial speed of 5.95 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision.
