Mechanics> a plane flying horizontally at aheight of...

a plane flying horizontally at aheight of1500m with avelocity of 200m/s passes directly overhead an antiaircraft gun.Then the angle with the horizontal at which the gun should be fired for the shell with a muzzle velocity of 400m/s to hit the plane is?

for y direcn.

1500 = 400sinthetha*t – 0.5gt^2................(1)

In x direcn.

x =400sinthetha*t.......................(2)

for plane,

x = 200*t...............(3)

I think only with solving eqns. (2) and (3)

U would get the answer.

t should be same in order to hit the bullet.

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.
