It is pulled to a distance x0 and pushed towards the centre with a velocity v0 at time t = 0. Determine the amplitude of the resulting oscillations in terms of the parameters ω,x0 and v0 ​ . [Hint : Start with the equation x=a cos(ωt+θ) and note that the initial velocity in negative.]

A mass attached to a spring is free to oscillate In Millikan's oil drop experiment The cylindrical tube of a spray pump has a cross-section of 8.0 cm^2 one end of which has 40 fine holes each of diameter 1.0 mm. If the liquid flow inside the tube is 1.5 m min^−1 Two narrow bores of diameters 3.0mm and 6.0 mm are joined together to form a U-shaped tube open at both ends. If the U-tube contains water what is the speed of ejection of the liquid through the holes ? with angular velocity ω
