At what angle a pratical is projected so that its height attained is equal to its horizontal range
1 Answer
NIKHIL GHODKE
we know the formula for max height and range height =(u sin(o))2/2grange=u2sin(2o) /g
also
sin(2o)=2sin(o)cos(o)
from rang eis equal to height we get
sin2 (o)/2=sin(2o)
sin2 (o)/2=2sin(o)cos(o)
sin(o)=4cos(o)
tan(o)=4

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
