railway RRB Technician Grade 1 Mock Test 2024 Physics Motion in a Straight Line Kinematic equations for uniformly accelerated motion
A bullet is shot vertically downwards with an initial velocity of 100 m/s from a certain height. Within 10s, the bullet reaches the ground and instantaneously comes to rest due to the perfectly inelastic collision. The velocity-time curve for total time t = -20s will be
(Take g = 10 m/s2)
