(b) A mechanic raises a \( 1200 \mathrm{~kg} \) car to check the components underneath by using an automotive lift and raises the car \( 2.0 \mathrm{~m} \) above floor level. The hydraulic cylinder inside the automotive lift has a \( 0.2 \mathrm{~m} \) diameter piston and \( 0.1 \mathrm{~m} \) diameter rod. Determine: i) the work required to lift the car, \( W(\mathrm{~J}) \) ii) the required pressure, \( P \) (Pa) iii) the power if the lift raises the car in \( 15 \mathrm{~s}, \bar{W}(\mathrm{~W}) \) iv) the ascending speed of the lift if the flow rate is \( 0.0005 \mathrm{~m}^{3} / \mathrm{s}, V(\mathrm{~m} / \mathrm{s}) \), and v) the flow rate for the lift to ascent in \( 10 \mathrm{~s}, Q\left(\mathrm{~m}^{3} / \mathrm{s}\right) \).

Given: mass m = 1200kg height h = 2 m diameter of piston d = 0.2m
