Heyya it's HEER here✌ solve it ✔™......☺

Answer 1

Answer:

Initial velocity u = g×t = 9.8×6 = 58.8 m/s

distance S1 travelled in first second is calculated using " S = u×t - (1/2)×g×t² ", using u = 58.8 m/s, and t = 1 s;

S1 = 58.8×1 -(1/2)×9.8×1²= 53.9 m

Since the paticle reaches maximum height in 6 s, at 7th second travel, its initial velocity is zero.

hence distance S7 travelled in 7th second = (1/2)×9.8×1² = 4.9 m

hence the ratio S1 / S7 = 53.9 / 4.9 = 11
