Solve: The pressure at the bottom of the vat is p = p0 + gd = 1.3 atm. Substituting into this equation gives
1.013 105 Pa + (9.8 m/s 2 )(2.0 m) = (1.3)(1.013 105 ) Pa
= 1550.5 kg/m3
The mass of the liquid in the vat is
m = V = (0.50 m)
14.9. Solve: The position of the object is given by the equation
x(t ) = A cos(t + 0)
The amplitude is A = 8.0 cm. The angular frequency = 2 f = 2 ( 0.50 Hz ) = rad/s. Since at t = 0 it has its
most negative position, it must be about to move to the right
