Hello, can you help me for this physics problem? I will have TE after the holidays, I need your help, many many thanks! A cyclist rides at constant speed on a loop circuit. From (1) to (2), the path is horizontal and it has the shape of a semicircle of radius R = 1250m. From (2) to (3), it is about a regular rise whose angle with the horizontal is 10. From (3) to (1), it is about a descent identical to the rise. The cyclist has a mass of 65kg, he moves at a constant speed of 18 km / h (form coefficient C = 0.8 and wind-catching surface S = 0.6 m ^ 2) (a)Determine the work done by each force . (b) We are looking for the power produced by the cyclist on the path between (1) and (2), then between (2) and (3). Between (3) and (1), the cyclist applies the brakes, this will be a dissipated braking power

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
