Project translated automatically. Log in or register, to view the original I need to solve 8 tasks they are short, all tasks are in the file I just need the solution and formulas you have solved, and the layout itself I will do myself.1 .How long can the body speed decrease from 8 m / s to 1 m / s with acceleration -2 m / s2?2ndCalculate the number of times the wheel turns, the normal acceleration is greater than its tangential acceleration at the point when the full acceleration vector of this point forms a corner of 30 ° with a linear speed vector?ThreeThe skive is attached to the top of two inclined plates.Places with the horizon form angles α = 30 ° and β = 45 ° (ris.2 to 4).Weight A and B, weight P1 = P2 = 9.8 N, are connected by three strings.Calculate 1) the acceleration with which the gyrus moves, 2) the strength limit of the string.Don’t pay attention to the treating shakes, as well as the weight of A and B. To solve the previous task, the treating coefficients of k1 = k2 = 0.1 for the weights of A and B. Don’t pay attention to the treating shakes?4 .On the inclined flat down to the top with the initial speed of 2 m / s, the corpus slides.As he climbs to some height, he climbs the same way back.How fast is the body returning to the starting point?The treating factor is 0.4, the inclination of the flat is 30 °.and 5.To determine the inertion and impulse of the Earth's ball relative to the turning axis?6 .One-line ball device in the form of a thread, the length of which is equal to the radius of the ball.How many times is the period of small fluctuations of this shell longer than the period of small fluctuations of the mathematical shell, if the distance between the point of hanging of the mathematical shell and its center of gravity is the same?7 .What acceleration and in what direction should the elevator move in a vertical flat so that the fluctuation period of the lm stone placed on its roof is 2.3 s?8 .Record the movement equation obtained from the sum of two harmonic fluctuations of the same direction with the same periods of 8 c and the same amplitude of 0.02 m.The phase difference between these fluctuations is π / 4.The initial phase for one of these fluctuations is zero.

by Edwin,
You have to clarify something - like the third string in the third task, what and where it is, if it is at all? In the 6th task, the thread is attached to the surface of the ball or otherwise? Call, I will explain everything, successfully prepared people for entry in the MFT and MGU.
