A lead object is dropped from a height of 10 m onto a hard floor. The object bounces, rising to a height of 0.8 m. The mechanical energy lost in the collision with the floor is all converted to thermal energy in the lead. Part A Find the change in temperature of the object after it first hits the floor. Assume that cpb = 126J/kgK ΑΣΦ ? AT= °C
