1.	A shell is fired vertically from a cannon which is travelling at constant speed u=30km/hr. the projectile leaves the connon with a velocity `v_(r)=20` m/s relative to the cannon . Show that the shell will land on the vehicle at the gun location and calcu late the distance by the vehicle during the flight of shell.
Answer» Correct Answer - s=34m `T=(2u)/(g)=(2xx20)/(10)=4` sec Distance travelled by the cannon. `s=30xx4xx(5)/(18)m` `s=120xx(5)/(18)` `s=(100)/(3)m`

Three balls A,B and C are projected from ground with same speed at same angle with the horizontal. The balls A,B and C collie with the wall during a flight in air and all three collide perpendicu lary and eleastically with the wall as shown in Fig. 5.119 it the time taken by the ball A to fall back on ground is 4 seconds and that by ball B is 2 seconds. Then the time taken by the ball C to reach the ground after projection will be:
