railway RRB Technician Grade 1 Mock Test 2024 Physics Motion in Two and Three Dimensions Projectile Motion
A gunman and an apple are both at height 98 m above the ground, at distance 200 m from each other. At t = 0, a bullet (m = 5 gm, velocity 200 m/s) is fired horizontally aimed at the apple. At the same time (t = 0) the apple starts to move downwards. Given g = 9.8 m/s2, the bullet will hit the apple only if it moves at constant
