3. A lead bullet (m=0.050kg & V= 5.00x106m) at 20.0°C impacts a block, made of an...
A 5.00-g lead bullet moving at 400 m/s penetrates a wood block and comes to rest inside the block. If half of its kinetic energy goes into heating the bullet, what is the bullet's change in temperature? The specific heat of lead is 128 J/ (kg*K).
A 24 g lead bullet traveling at 360 m/s penetrates a 1.4 kg lead block and stops. By how much does the temperature of the block and bullet increase If all the kinetic energy of the bullet is absorbed. (Use cPb= 128 J*K/kg) DT= Kelvin
A 18 g lead bullet is tested by firing it into a fixed block of wood with a mass of 36 kg. The block and imbedded bullet together absorb all the heat generated. After the thermal equilibrium has been reached, the system has a temperature rise measured as 0.019 degrees celcius. Estimate the entering speed of the bullet. v=
A 3.00 g bullet moving at 115 m/s strikes a 50.0 g stationary wooden block and embeds itself in the block. The bullet is made of lead, and the specific heat of lead is 128 J/(kg · °C). Assume the thermal energy generated in the collision is equally distributed in the bullet and the block. (a) Calculate the rise of temperature (T) of the bullet if block is clamped in place so that it cannot move. (b) Calculate the rise...
A 0.06-kg lead bullet traveling 151 m/s strikes an armor plate and comes to a stop. If all of the bullet's energy is converted to heat that it alone absorbs, what is its temperature change?
A 0.07-kg lead bullet traveling 170 m/s strikes an armor plate and comes to a stop. If all of the bullet's energy is converted to heat that it alone absorbs, what is its temperature change?
A 50.0-gram lead bullet hits a steel plate, both initially at 25 °C. The bullet melts and splatters on impact. Assuming that the bullet receives 88% of its kinetic energy as heat energy, at what minimum speed must it be traveling to melt on impact? (The melting temperature of Lead is 327°C)
A 90.0-gram lead bullet hits a steel plate, both initially at 29 °C. The bullet melts and splatters on impact. Assuming that the bullet receives 76% of its kinetic energy as heat energy, at what minimum speed must it be traveling to melt on impact? (The melting temperature of Lead is 327°C)
A 90.0-gram lead bullet hits a steel plate, both initially at 24 °C. The bullet melts and splatters on impact. Assuming that the bullet receives 74% of its kinetic energy as heat energy, at what minimum speed must it be traveling to melt on impact? (The melting temperature of Lead is 327°C) _____ m/s
A 3.00 g bullet moving at 115 m/s strikes a 50.0 g stationary wooden block and embeds itself in the block. The bullet is made of lead, and the specific heat of lead is 128 J/(kg · °C). Assume the thermal energy generated in the collision is equally distributed in the bullet and the block. (a) Calculate the rise of temperature (DeltaT) of the bullet if block is clamped in place so that it cannot move. (b) Calculate the rise...
