So far in this tutorial, you have been launching a pumpkin. let's see what happens to the trajectory if you launch something bigger and heavier, like a car. compare the trajectory and range of the pumpkin to that of the car, using the same initial speed and angle (e. g., 45∘). (be sure that air resistance is still turned off.) which statement is true? so far in this tutorial, you have been launching a pumpkin. let's see what happens to the trajectory if you launch something bigger and heavier, like a car. compare the trajectory and range of the pumpkin to that of the car, using the same initial speed and angle (e. g., ). (be sure that air resistance is still turned off.) which statement is true? the trajectories differ; the range of the car is longer than that of the pumpkin. the trajectories differ; the range of the car is shorter than that of the pumpkin. the trajectories and thus the range of the car and the pumpkin are identical.

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.
