What does the data mean? * The car and the truck have different masses and velocities.
The car and the truck's momenta are determined by different masses and velocities that equal the same product when multiplied together. Masses and velocities don't have to be the same to get the same momentum.
The car and truck have the same momentum.
The car and the truck have a different momentum.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
