1.	In Fig. 98 m and H=98 m. A rigid uniform sphere starts from the point A from rest and rolls down the track without slipping and reaches the horizontal right hand end B, What is the distance to the right of the point C at which the sphere strikes the horizontal base line ?(given h=29.4)
Answer» SOLUTION :`mgh =(7//10)MV^(2), v=sqrt(9.8 XX 68.6 xx 10//7) = 31 m//s, t = sqrt(2 xx 29.4//9.8) = 2.4 s`. DISTANCE `=31 xx 2.4 = 74.4`m
