An ice cube density =917kg/m3,is sliding down a frictionless in line . The sides of the cubes each hace a lenght of 0.75 m. What pressure does the cube exert on the line?

• Pressure = Force / Area
= V * ρ * g / A

= a3 * ρ * g / a2

= a * ρ * g

= 0.75 * 917 * 9.81 = 6746.8275 Pa

• given,

rho =917kg/3,

l=0.75m,

P = F/A

force exerted = mg= vol.density.g

= s^3 X?ho X g / s^2

= s X ?ho X g

= 0.75X917X9.81

= 6746.8275 Pa (ressure does the cube exert on the line)
