As part of a lubricating system for heavy machinery, oil of density 850kg/m^3 is pumped through a cylindrical pipe of radius 8cm at a rate of 9.5L per second.
what is the speed of the oil?

what is the mass of flow rate?

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
