(1 point) A hot metal bar is submerged in a large reservoir of water whose temperature is 60°F. The temperature of the bar 20s after submersion is 100°F. After 1 min submerged, the temperature has cooled to 80°F. (a) Determine the cooling constant k (b) What is the differential equation satisfied by the temperature F(t) of the bar? F' (t) = Use F for F(t). (c) What is the formula for F(t)? F(t)= (d) Determine the temperature of the bar at the moment it is submerged. Initial temperature = °F (1 point) A hot metal bar is submerged in a large reservoir of water whose temperature is 60°F. The temperature of the bar 20s after submersion is 100°F.
