# A particle is projected at an angle 60 degree,with speed 10sqrt3m/s from the Point A towards right.At the same time the wedge (HAVING ITS FOOT of inclination 30 degree at A) is made to move with speed 10sqrt3m/s towards right.Then the time after which the particle will strike with the wedge is(a)2s(b2sqrt3 m/s(c)4/sqrt3 m/s(d)none .............

dear Rajan

resolve the velocity of projectile

Ux= 10√3 COS60= 5√3

Uy=10√3 sin60=15

now you can see that horizontal velocity of wedge is more than the projectile hence they will not meet.

All the best.

Relative se solve kar, ban jayega.Wedge ko rest mein la,Wedge ki velocity projectile ke horizontal component ko opposite direction mein de, fir solve kr ...and ans is 2 sec
