A bicycle tire of radius 0.40 m and mass 1.7kg is rotating at 62.9 rad/s. What torque is necessary to stop the tire in 2.2 s?
Answer in units of N · m.
I asked this before but it got answered by a bot who links a virus website. Can someone please help me?

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
