    Thanks for your working but I was asking why the acceleration of bodies don't have opposite signs ? o_O I mean when they are in opposite directions shouldn't one be +ve and one -ve ?

    For 1 ii.) Use a = gSinα and replace the values of a and g then you will get the value of α. For 4. iii.) Use the equation mgh = 0.5mv^2 and replace the values of m, and v (i.e v = 8 ) and perform the necessary calculations. Then you will get the actual value of h.

    The lowest value of H is 2.45 at point M. Look at the left hand side of the figure and you will understand it.

    A body will have greatest speed when its kinetic energy is highest and kinetic energy will be highest when P.E is lowest. So use mgh = 0.5mv^2. And put the lowest possible value of h i.e 2.45m. For the ii.) part use K.E = P.E lost but use h = 2.45 - 1.2 while calculating P.E because it is the...
