Q1. A hunter aims directly at a target (on the same level) 84.2m. If the bullet leaves the gun at a speed of 193 m/s, by how much will it miss the target?
Q2. An engine is approaching a hill at a constant speed. When it is at distance of .7 km, it blows a whistle, whose echo is heard by the driver after 5 sec. If the speed of sound is 350m/s, compute the speed of engine.
