QUESTION 19 A 0.02 kg lead bullet traveling 201 m/s strikes an armor plate and comes...
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 0.045 kg aluminum bullet traveling at 471 m/s strikes an armor plate and comes to a stop. If all its energy is converted to heat that is absorbed by the bullet, what is the bullet's temperature change in degrees Celsius?
A 0.047 kg aluminum bullet traveling at 459 m/s strikes an armor plate and comes to a stop. If all its energy is converted to heat that is absorbed by the bullet, what is the bullet's temperature change in degrees Celsius?
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 4.00-g lead bullet is traveling at a speed of 200 m/s when it embeds in a wood post. If we assume that half of the resultant heat energy generated remains with the bullet, what is the increase in temperature of the embedded bullet? (specific heat of lead = 0.0305 kcal/kg⋅°C, 1 kcal = 4 186 J)
3. A lead bullet (m=0.050kg & V= 5.00x106m) at 20.0°C impacts a block, made of an ideal thermal insulator, and comes to rest at its center. After impact, the temperature of the bullet is 327.0°C. The specific heat capacity of lead is 128J/kg-K. a. Determine the heat absorbed by the bullet during its temperature change. b. What is the final volume of the bullet just after it comes to rest? c. How fast was the bullet traveling prior to hitting...
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
Lend has a specific heat of 128 J/kg°C. A lead bullet is moving at 650 m/s. If the bullet is suddenly stopped so that all of its kinetic energy is converted into heat, determine the temperature that the lead bullet reached before it was stopped. Take the initial temperature of the bullet to be 30 °C.
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...
