hello I need help solving those questions please!

0 H A long, thin uniform rod of length 2.06m and mass 3.38kg is pivoted about a horizontal, frictionless pin passing through one end. The rod is released from one end in the vertical position. \\ Punt At the instant the rod is horizontal, find its angular speed. Submit Answer Tries 0/10 At the instant the rod is horizontal, what is its angluar acceleration? Submit Answer Tries 0/10 At the instant the rod is horizontal, what is the magnitude of its x-component of acceleration at its centre of mass? Submit Answer Tries 0/10 At the instant the rod is horizontal, what is the magnitude of its Y-component of acceleration at its centre of mass? Submit Answer Tries 0/10 0 a The top shown in the gure below has a moment of inertia of 3.19E-4kg-mZ and is initially at rest. It is free to rotate about the stationary axis AA'. A string, wrapped around a peg along the axis of the top is pulled in such a manner that a constant tension of 5.37N is maintained. If the string does not slip while it is unwound from the peg, what is the angular speed of the top after 77.7cm of string has been pulled off the peg? Submit Answer Tries 0/10 A. 3" i F ._( w 9 _/ 1' . A ' ' '1 A 4.08kg particle moving along the x-axis experiences the force shown, where Fmax = 4.14N, Fm," = -4,14N, d1 = 2.15m, d2 = 4.30m, d3 = 6.45m, and d4 = 8.60m. At x = 0.00m the particle's velocity is 4.10m/s. F(N) x(m) min What is its velocity at x=4.30m? Submit Answer Tries 0/10 What is its velocity at x=8.60m? Submit Answer Tries 0/10 0 a (10)(a) How much work does an elevator motor do to lift a 1292.0 kg elevator a height of 57.2 m? Submit Answer Tries 0/10 (b) How much power must the motor supply to do this in 58.0 s at constant speed? Submit Answer Tries 0/10 0 a (3) A horizontal spring with spring constant 89.9N/m is compressed 18.2cm and used to launch a 5.79kg box across a frictionless, horizontal surface. After the box travels some distance, the surface becomes rough. The coefficient of kinetic friction of the box on the surface is 0,474. How far does the box slide across the rough surface before stopping
