Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

A great pianist is getting ready for his concert and plan to move his exclusive grand piano to his concert venue. The 700 kg piano needs to be loaded onto a truck bed which is about 1.5 m high.1.Initially, the movers decide to use an adjustable ramp to move the piano. The ramp can only be adjusted up to 10 m long and the inclination angle must not exceed 20° to ensure a safe loading process. Determine the range of a suitable length and angle of the ramp. 2.On a second thought, the movers are considering whether it is easier to lift the piano straight up onto the truck bed or push it up along the rough the ramp. With the aid of an appropriate free body diagram, justify the most efficient option for the movers to load the piano to the truck bed with constant speed. State clearly all the assumptions made, and the principles used in the calculations to support your answers.

An electric drill has an average useful output power of 55 W during 0.45 s of operation. The power output of the drill is transferred to a brick that has a specific heat capacity of 850 J/kg⋅K and a mass of 1.5 kg. The drill and the brick are initially at the same temperature. Because of friction, the brick increases in temperature by 0.012 K while in contact with the drill bit. What is the net useful work done on the brick by the drill if the drill bit is heated by 0.25 J? Give your answer to one decimal place.
