Question
Initially at rest. The bullet emerges from the block moving upward at 400 m/s. To what maximum height does the block rise above its initial position? **53 In Anchorage, collisions of a vehicle with a moose common that they are referred to with the abbreviation Suppose a 1000 kg car slides into a stationary 500 kg moc very slippery road, with the moose being thrown through th shield (a common MVC result). (a) What percent of the kinetic energy is lost in the collision to other forms of en similar danger occurs in Saudi Arabia because of camel collisions (CVC). (b) What percent of the original kinetic lost if the car hits a 300 kg camel? (c) Generally, does the loss increase or decrease if the animal mass decreases? **54 A completely inelastic collision occurs between two wet putty that move directly toward each other along a axis. Just before the collision, one ball, of mass 3.0 kg. is m ward at 20 m/s and the other ball. of mass 2.0 kg. is movi ward at 12 m/s. How high do the combined two balls of above the collision point? (Neglect air drag.)Explanation / Answer
Delta K / K1=K1-Kf /k1=mc /mc+mm =500 /1000+500=1/3 =33.3%
(b) If the collision were with a camel of mass
Camel 300 kg,
Delta K / Ki= =300 /1000+300=3/13 =23%
