A particle is projected horizontally with velocity 10 ~m / s from an inclined plane. Incline plane starts moving with acceleration 10 ~m / s ^2 vertically upward as shown. The time (in second) after which particle will land on the plane is given by 1 n ~s . Find the value of n . ( g =10 ~m / s ^2 )

Correct answer

3

Step-by-step solution

Acceleration of ball w.r.t. plane aligned & a _ bp = a _ bg - a _ ps =2 ~g (downward) & s = ut + 1 2 at ^2 0= (10 30^ ) t - 1 2 (2 ~g 30^ ) t ^2 & t =1 / O 3 aligned
