Answer 1

1 . Oball 045 since i when we throw a ball upward jg acceleration due to gravity acts opposite to the direction of velocity gd7 HIT Ground then The velocity at a find point is zero so using @ V2-42 - 2as. ang, uz tog 20 0.- =-2gs 25 x 25 l 2 x 9.8 ' using u- 25 m/s & ga 9.8 m/s² Hieght of ball Is= 63.77m Le (b) sa ut tlak . By using n= ut at for a upward motion não , a=-g 0-gt, t, y = 25 = 2.55 sec 9,- 2,55 sec Time taken to reach the highest point a .

(c) o uzo | for downward motion initial speed = zero , a=g By using S = ute that? or s = £ gta gu. ve = 2x 63.77 9.8 +2= 3.60 see using v=utat U=O Ne gt le = 9.8 x 3.6 v 3 35.35 m/s) final velocity v is
