- Mike then takes his now 1175 kg car and crashes it at 50 m/s into the back of a 1600 kg Jeep traveling at 10 m/s. They roll off together going 18 m/s. How much work was done by the crumple zone of Mike’s car? Just a short simple answer will suffice.At t= 0st= 0s you launch a lump of sticky clay with mass m1= 13kgm1= 13kg and velocity 7m/s i^7m/s i^ directly toward a block of mass m2= 31kgm2= 31kg that is sliding directly toward the clay with a velocity of −9m/s i^−9m/s i^ . The clay sticks to the block completely. How much kinetic energy was lost during 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 50-g ball is shot into a chamber attached to a 500-g cart. After the collision the ball/cart combination moves away with a speed of 3.0 m/s. Assuming that friction and air resistance are negligible, determine the amount of energy lost in the collision.Toy car 1 of mass 250 gram and velocity 0.25 m/s and toy car 2 of mass 350 gram and velocity 0.20 m/s are moving on the same track in the same direction. After collision, car 1 moves with velocity 0.15 m/s. (a) What is the velocity of car 2? (b) How much thermal energy is generated during the collision?A 0.015-kg bullet is fired into a stationary block of wood of mass of 5.2 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded on the block of wood). If the speed of the bullet before collision is 462 m/s, what is the kinetic energy of the bullet plus-wood combination right after the collision? Assume no change in the potential energy of the system before and after the collision. Express your answer in two decimal places, in Joules.
