I. Pushing on a File Cabinet
Bob has been asked to push a heavy file cabinet down the
hall to another office. It's not on rollers, so there is a lot
of friction. At time t = 0 seconds, he starts pushing it
from rest with increasing force until it starts to move at t
= 2 seconds. He pushes the file cabinet down the hall
with varying amounts of force. The velocity versus time
graph of the cabinet is shown below.
A. On the graphs provided below,
1. draw the net force vs. time that would produce this velocity graph;
2. draw the friction force vs. time for this motion;
3. draw the applied force (Fon Cabinet by Bob) VS. time for this motion (the first two seconds of this graph
have been drawn for you).

- Part A: kg (a) Water at 20 °C (p = 998.3 and v = 1 × 10-6 m²/s) flows through a galvanised m³ iron pipe (k = 0.15 mm) with a diameter of 25 mm, entering the room at point A and discharging at point C from the fully opened gate valve B at a volumetric flow rate of 0.003 m³/s. Determine the required pressure at A, considering all the losses that occur in the system described in Figure Q1. Loss coefficients for pipe fittings have been provided in Table 1. [25 marks] (b) Due to corrosion within the pipe, the average flow velocity at C is observed to be V2 m/s after 10 years of operation whilst the pressure at A remains the same as determined in (a). Determine the average annual rate of growth of k within the pipe. [15 marks] 4₁ Figure Q1. Pipe system Page 2 25 mmarrow_forwardFor an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 53.5 km due east and have it detected by a light sensor that is 119 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west.(b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light.arrow_forwardA mirror hangs 1.67 m above the floor on a vertical wall.
