[Take g =10ms-2 where applicable] Question Two Two particles P and Q have masses 7 m and Fm respectively, where F>7. The particles are connected by a light inextensible string which passes over a smooth light fixed pulley. The system is held at rest with the string taut, the hanging parts of the string vertical and with P and Q at the same height above a horizontal plane as shown. The system is released from rest. After release, P descends with acceleration 5g. (a) State how you used the information that the pulley is smooth. (b) After descending for 1.2sec, the particle A reaches the plane and brought to rest. IfB does not reach the pulley in the subsequent motion, find the greatest height reached by B above the plane.

hi would you be able to answer the below question g please?
Hi looking for help with problem 2, thank you
Question 3 The position F of a particle moving in an xy plane is given by: F =(2.00t – 5.00t)i +(6.00–700*)} with F in meters and t in seconds. (Note that this is an example where the units for the coefficients are ignored – don't let this distract you!) In unit vector notation, calculate: а). r b). V с). а for t = 2.00 s. d). What is the angle between the positive direction of the x axis and a line tangent to the particle's path at t= 2.00 s?

Find X(s)/U(s) Transfer Function of the system below and please interpret physical response of the system for c=5 N-s/m k=10 N/m and m-5 kg u(t)=15 N. After that design the dynamic model of the system on MATLAB/Simulink and compare it with your interpretation. x(t) u(t) k
Full work for question 1
I am am doing problem 5. from Serway and Vuille - 11th edition. I dont understand why they use sin 30 and not cos 30 when the fomula for work = (F cos (theta)). d. Is there away way you could draw a diagram to help explain it to me? cheers.
for the second question, i only need help with part c
Please help me explain e and g. I’m really confused about it.
Part c) In the problem of the three coupled pendula, consider the three coupling constants as distinct, so that the potential energy may be written as 1 U (0} + 0 + 0 – 28128,02 – 2€1,0,03 - 2ɛ 230 20 3) With, &12, E13, E23 , different. Show that no degeneracy occurs in such a system. Show also that degeneracy can occur only if ɛ12= E13= E23.
Please explain well
