A company has a contract to build a sewer in a nearby province, it must dig a ditch 2m wide, 1m deep, and 2000m long. Laborers are available at P 120/day for an 8-hr day work and can dig at an average of 0.5 cu-m per hr. A ditchadigging machine maybe rented at a cost of P 1,500 a day for all the time it is in use or in transit. One day would be required for transporting the machine one way. Freight cost would total P 4,000. The machine operator would be paid P350/day including travel time for two days. If the machine is used, three laborers are needed. The ditch digging machine can excavate 1 cu-m in 6 min. All workers and machine rentals must be paid on full 8-hr a day basis. What would you recommend and by how much it must cost?

of the slope. b) Calkulate the net force that acts on the skateboarder as he moves down the slope a Calculate the work done by the net force, as the skateboarder moves 36 m down the slope. Fig 4.42: A skateboarder skates down a slope ind at 25° to the horizontal. d) Use the work-energy theorem to calculate the initial velocity of the skateboarder near the top of the slope. In Figure 4.43, a 3 kg block slides at a constant velocity of 7 m.s along a horizontal surface. It then strikes a rough surface, causing it to experience a constant frictional force of 30 N. The block slides 2 m under the influence of this frictional force before it moves up a frictionless ramp inclined at an angle of 20° to the horizontal, as shown. 7 m,s-1 3 kg of 20 2 m Fig 4.43: A block moves horizontally and then up a slope. a) Use the work-energy theorem to show by calculation that the speed of the block at the bottom of the ramp is 3 m.s-. b) Draw a free-body diagram to show the fòrces acting on the block…
A brand-new pick-up truck was driven and tested on a national highway. Due to a very light traffic, 8hp is highly required to drive the said vehicle with a mass of 1800kg at a speed rate of 60kph.
