An object is sitting at rest. we call its location (0,0). two concurrent forces are applied on the object. they are a. F1 = 30n at 40 degrees
b. F2 = 10n at 200 degrees

Give the net force acting in the object in
a) free body diagram
b) Vector and Magnitude Form
c) Component Vector Form

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.

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?
