Estimate the speed that a lead bullet must have in order that it melts completely when it strikes a target. Assume that all the bullet’s kinetic energy goes into heat and that the bullet is initially at 20oC. The specific heat capacity of lead is 130 J / (kg oC), its melting point is at 327oC its latent heat of fusion is 24.5 kJ/kg.

A lead bullet of unknown mass leaves a rifle at a temperature of 87 C and hits a steel plate. Upon impact exactly half of the bullet's mass melts. Assume that only 40% of the bullet's initial kinetic energy goes into increasing its temperature and then partially melting it. What was the initial speed of the bullet? melting temperature of LEAd: 327 C specific heat of Lead: 0.13E3 J/(Kg.K) Latent heat of fusion: 22.9E3 J/kg

A lead bullet is shot down from the altitude of 100 m above the ground. What must be the minimal initial velocity of the bullet so that it completely melts after a perfectly inelastic collision with the ground? The initial temperature of the bullet is 500 K, melting temperature of lead is 600 K. Speci c heat capacity of lead is c = 130 J/(kgK), speci c heat of fusion of lead is r = 24 kJ/kg. The heat released...

An 0.025 kg bullet traveling at 700 m/s strikes and passes through the center of mass of a 0.50 kg block of wood that is initially at rest on a smooth flat surface. The bullet passes through the block and emerges from the other side traveling at 300 m/s? How fast will the block be sliding just after the bullet emerges, and how much energy (in Joules) will be converted to heat? (Neglect the effect of sliding friction during the...
