An amusement park ride consists of a rotating
circular platform 7.89 m in diameter from
which 10 kg seats are suspended at the end
of 3.49 m massless chains. when the system
rotates, the chains make an angle of 34.4
◦ with
the vertical.
the acceleration of gravity is 9.8 m/s

what is the speed of each seat?
answer in units of m/s

a car accelerates uniformly from rest and
reaches a speed of 34.8 m/s in 12.4 s. the
diameter of a tire is 92.6 cm.
find the number of revolutions the tire
makes during this motion, assuming no slipping.
answer in units of rev.

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.
