34.- A car with a mass of 1800 kg is stopped at a traffic light, it is hit by a compact car with a mass of 900 kg, the cars are entangled after the collision.
a) If the compact car was moving at 20 m/s before the collision, what will be the velocity of the entangled mass after the collision? b) How much
kinetic energy is lost in the collision?
35.- Two identical particles have the following speeds before the collision v_(0_A )=-20r m/s and v_(0_B )=20j m/s. They collide at the origin of
coordinates in such a way that after the collision the speed of the ball A is v_A-10 m/s. What is the magnitude and direction of ball B after the
collision?
