Initial momentum = 0.15 kg * (-5 m/s) = - 0.75 N*s

final momentum = 0.15 * ( 3 m/s) =  0.45 N*s

Change in momentum = final momentum - initial momentun =

= 0.45N*s - (- 0.75N*s) =  1.2 N*s

Answer:  1.2 N*s

Mercury is added to a cylindrical container to a depth d and then the rest of the cylinder is filled with water. If the cylinder
jonny [76]

Answer:

0.10839 m

Explanation:

P_1 = Atmospheric pressure = 1 atm = 101325 Pa

P = Total pressure at bottom of mecury = 1.2 atm

g = Acceleration due to gravity = 9.81 m/s²

h = d = Depth of mercury

\rho_m = Density of mercury = 1.36\times 10^4\ kg/m^3

\rho_w = Density of water = 1000\ kg/m^3

Pressure at the bottom is of the cylinder is given by

P_2=P_1+\rho_wgh\\\Rightarrow P_2=101325+1000\times 9.81(0.7-d)

Pressure at the bottom of mercury is

P=P_2+\rho_mgh\\\Rightarrow 1.2\times 101325=101325+1000\times 9.81(0.7-d)+1.36\times 10^4\times 9.81\times d\\\Rightarrow 1.2\times 101325=123606d+108192\\\Rightarrow d=\dfrac{1.2\times 101325-108192}{123606}\\\Rightarrow d=0.10839\ m

The depth of the mercury is 0.10839 m
