3 speed may increase 4 With positive value of acceleration speed must increase A drunkard walking in a narrow lane takes 5 h steps forward 3 steps backward and then ON stay for 1 s and repeat the same process again and again Each step is 1 m long and takes 1 s The time taken by drunkard to fall in a pit 10 m away from start is NCERT Pg 56 1 45 s 3 30 s 2 27 s 4 31 s In any realistic condition v t graph cannot have sharp kink points This implies that NO 1 Both velocity and accel change abruptly at an insta 2 Both velocity and acceler change abruptly at an insta 3 Only velocity cannot chan an instant but acceleration 4 Orly acceleration ca abruptly at an instant b change
