Your brother is working as a supervisor in a beverage bottling plant. One day, he let
you tour around the facility. You noticed that a beverage (mostly water) flows in a
pipe with a mass flow rate that would fill 220 cans every minute. Each can contain
355-mL of the liquid. At point 1 in the pipe, the gauge pressure is 152 kPa and the cross-sectional area is 8.00m². At point 2, 1.35 m above point 1, the cross-sectional area is 2.00m². Calculate the (A) mass flow rate; (B) volume fllow rate; (C) flow speeds at the two points; (D) gauge pressure at point 2.

An external force acting on a particle of mass m in one dimension is
given by F = βt2 where β is a positive constant. If the initial speed of the particle is
v1 (at t = 0) and its final speed is v2 at t = tf . Find constant β in terms of the given
quantities.
A box (very small) was propelled up an inclined plane. The propelling agent is no longer acting on the box as it moves up the incline. The coefficients of static and kinetic friction for the box/plane interface are 0.4 and 0.2 respectively. The initial speed of the block G the bottom of the incline is 63m/s. The block slides up the plane and becomes a projectile. How high will the box fly and where will it impact the ground?
