Q. A bullet is shot vertically downwards with an initial velocity of $100 m / s$ from a certain height. Within $10 s$ , the bullet reaches the ground and instantaneously comes to rest due to the perfectly inelastic collision. The velocity-time curve for total time $t = 20 s$ will be : $($ Take $g = 10 m / s^{2})$
