    V=omega*underroot Square -xsquare. Here X is root 3/2 A put value in the formula and you get omega*A/2 and as at mean position velocity is omega*a the at root3/2 distance it is v/2

    Q: 

    A ball is thrown from a roof top at an angle of 45° above the horizontal. It hits the ground a few seconds later. At what point during its motion, does the ball have . 
    (a) greatest speed
    (b) smallest speed
    (c) greatest acceleration Explain. 

    In this problem total mechanical energy of the ball is conserved. As the ball is projected from point O, and covering the path OABC. At point A it has both kinetic and potential energy. But at point C it have only kinetic energy, (keeping the ground as reference where PE is zero.)
    (a) At point B, it will gain the same speed u and after that speed increases and will be maximum just before reaching C.
    (b) During upward journey from OtoA speed decreases and smallest speed attained by it is at the highest point, i.e., at point A.
    (c) Acceleration is always constant throughout the journey and is vertically downward equal to g.

    One more thing add the the velocity of all the dimension of the molecules. It means let v1 is velocity in One Direction v2 in y and v3 in z then v1square +v2 square +v3square is the the total velocity. Now substitute it in the equation you will get m*vsquare/2/ here v is the total velocity of one molecule

    Sudarshan Sharma 6 years, 9 months ago

    2l/v time for 1 collisions then v/2l for collisions in one second v/2l*2mv=mv*v/l change in momentum in 1 second now force on wall by one molecule is change in momentum =mv*v/2l where v is the velocity of a molecule in one dimension similarly you can add the momentum change of all n molecules to get the total force.

    according to this theorem when three concurrent forces f1,f2 and f3 acting on a body in equilibrium then three concurrent forces acting at some angles.f1/ sin alpha =f2/sin beta=f3/sin gamma.

    It is sine rule if the forces are equilibrium then the force vectors will form a closed triangle which means that there resultant is zero .

    If you want, you can use the calculus of variations to find a steady-state y minimizing potential energy. It is not too hard: take the correct expression U=∫dx(F(x)y(x)−YI[y′′(x)]2)U=∫dx(F(x)y(x)−YI[y″(x)]2) and replace y(x)→y(x)+δy(x)y(x)→y(x)+δy(x), looking for δU=∫dx(F δy−Y I [(y′′+δy′′)2−(y′′)2])=0δU=∫dx(F δy−Y I [(y″+δy″)2−(y″)2])=0. Ignoring (δy′′)2(δy″)2 you integrate by parts twice: ∫dx(F−Y I y′′′′)δy=0∫dx(F−Y I y⁗)δy=0 can only be 00 for all δyδy if F=Y I y′′′′.F=Y I y⁗. (But, F(x) does have a δ function

    (i) The angular momentum of a particle with respect to a point gives an idea of the strength of its rotational tendency about that point.
    (ii) The magnitude of the angular momentum is defined in terms of mass and velocity of the particle and its distance from the reference point, i.e.,
    L = mvr
    (iii) The vector concept of the angular momentum is useful. Its direction is the axial direction given by right hand rule.
