    2009 hsc paper

    hey im a bit confused for 2009 hsc paper multiple choice question 5 the answer is D but the measurement is 7.3cm x100 = 7.3m the answer is 8m. I think it is because it takes more wire to hold the beam in place? I just thought it was logical but not 100% sure if it is correct. Edit...

    projectile motion

    a ball is thrown with initial velo 20m/s at an angle of elevation arc tan (4/3) Suppose that the ball is thrown up a road inclined at arc tan (1/5) to the horizontal. Show that: The time of flight is 2.72 secs, and find the distance the has been thrown up the road. Additional info you might...

    shm agn

    A particle is moving with SHM of period pi seconds and max velo 8m/s. If the particle started from x = a, find a , then find the velo when the particle is distant 3m from the mean position. x.. = -n^2x or x.. = -n^2(x-x0) damn i fail at this topic :haha:

    shm

    The amplitude of a particle moving in shm is 5m, and its acceleration when 2m from its mean position is 4m/s^2. Find the speed of the particle at the mean position and when it is 4m from the mean position. answer 5root2 m/s, 3 root2 m/s (how do you get this..) i did : x=a sin(nt+A) => when x...

    shm

    the velo of a particle is proportional to its displacement. When t = 0 , x=2, and t = 10, x = 4. Find the displacement- time function, and find the displacement when t = 25. i dont understand the part in bold i interpreted it as v = x? dx /dt = x??

    rates of change

    the flow of water into a small dam over the course of a year varies with time and is approximated by dW / dt = 1.2 - cos^2 pi/12t, where W is the volume of the water in the dam, measured in thousands of cubic metres, and t is the time measured in months from the beginning of jannuary. What is...

    Modern reader

    Discuss the value of Hamlet's delay for action, and the value it has for the modern reader. (TEXTUAL INTEGRITY) Dot point form will be fine, just want a brain storm so i can link all my ideas together. any synthesis will be more appreciated :music:

    trig

    find the max and min values of the expression (2-sin@)/cos@ for 0<_@<_pi/4 and state the values of @ for which they occur i obtain pi / 6 but am not sure how to get @ = 0 as well, and you have to double diff to show max min right, full working please

    trig

    Prove algebraically that if n is a solution of the equation 2cosx = 1 - .5x, then -2 <_n<_6. when showing this graphically is the negative solution(3 solutions) on the left of y axis or right of y axis. The answer at the back of book says on the left, but that is above the x axis meaning y>0...
