then the condition for it to land perpendicular the plane is 2tan(b-a)=cota
if the projectile land on the surface horizontally(parallel to ground ) then tanb = cota+2tana
it can be easily derived from the formulas of motion on inthe inclined plane such as
x=ucos(b-a)t -(1/2)gsin(a)t^2
y= usin(b-a)t-(1/2)gcos(a)t^2
by appling the condition.
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.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
