the length of a pendulum is 25 cm, and the mass of the bob is 300 g. it is displaced from the equilibrium position and released. at the lowest point of the trajectory the ke of the pendulum is 0.265 j.

a. how fast is the pendulum moving when at the lowest point?

b. from what height (above the lowest point of the trajectory) was it released?

c. what is the total mechanical energy of the pendulum?

d. the pendulum is passing through a point 5 cm above its equilibrium position (its lowest point).

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.
