Consider a cricket ball, with a mass of 0.17kg, travelling at a speed of 37.9m/s. the batsman hits the ball back in the opposite direction to that when it hit the bat. the ball returns at a speed 20.0 after it hits the bat. if the ball and bat are in contact for 90.5 milliseconds, what is the size of the net force applied to the ball during this collision, in newtons?

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.
