    Classical Mechanics Kleppner Problem

    Yes, it does. the answer comes as 8L/3 and this gives the centr of mass cordintes as (2L,0) The trick is if we take assume velocities (like I did) it is important to define wrt to ground. The relation that i derived for the velocities is correct but it is wrt to each other. Hence V(s)xt is not...

    Classical Mechanics Kleppner Problem

    V - velocity of unbroken piece. V(s)- velocity of smaller piece V(l)- Velocity of larger peice. t(f)- time of ascent or descent all velocities in x axis. before explosion momentum = MV after explosion momentum = M/4 x[V-V(s)]+ 3M/4[V(l)+V] equating and removing M and solving we get 3V(l)=...

    wait let me show you the momentum conservation that I had applied

    Classical Mechanics Kleppner Problem

    The smaller piece comes back top the launching station. Hence the V(s)/V(l)= 3/1 IF V(s)xt= L then it implies that V(l)xt =L/3.

    Classical Mechanics Kleppner Problem

    My apologies. I had made an error in typing. It is the smaller piece that returns back to the launching station. Thinking in terms of the conservation of momentum of center of mass. My answer seems correct. The centre of mass must be at the distance of L as it falls freely. But shouldn't it...

    Classical Mechanics Kleppner Problem

    An Instrument carrying a projectile accidentally explodes at he top of its trajectory.The horizontal distance b/w the launch point and the point of explosion is L. The projectile breaks into 2 pieces which fly horizontally apart. The larger piece has three time the mass of the smaller one and...

    Gravitational Acceleration and Determining Height

    the time will be in sec and that is the time taken for the ball to reach the top of the truck. Now use s= ut+1/at^2 where u=0 and t is the calculated time

    Gravitational Acceleration and Determining Height

    since the truck is not accelerating we don't need to use the equation of motion. s= ut+1/at^2 convert 55km/hr into m/s and find out the time for the truck to cross. s=vxt
