A ball connected with string is released at an angle 45 degree with the vertical as shown in the fig. then the acceleration of the box at this instant will be (mass of the box is equal to the mass of the ball)
a) g/4 b) g/3 c) g/2 d) g
a) g/4
b) g/3
c) g/2
d) g
The force acting towards the centre initially is Tsin45. its horizontal acceleration towards the centre is given by a=gtan$ i.e. a=g applying conservation of momentum mu=2mv i.e. v=u/2 differentiating.... a1=a/2 i.e acceleration of block is g/2
