A Block of Material of Mass M and Specific Heat $\Delta T = \frac { v ^ { 2 } } { 2 c }$

question 59

Multiple Choice

A block of material of mass m and specific heat c falls from height h and reaches speed v just before striking the ground.Its temperature is measured immediately after it strikes the ground.If we ignore any change in temperature owing to interaction with the air,the change in temperature of the block of material is

• A) \(\Delta T = \frac { v ^ { 2 } } { 2 c }\) .
• B) \(\Delta T = \frac { g h } { c }\) .
• C) \(\Delta T = \frac { v g h } { c }\) .
• D)All of the answers above are correct.
• E)Only (a)and (b)above are correct.
