1.	Question A ball falls vertically after beingdropped. The ball falls a distance d metres in a time of t seconds. d is directly proportional to the square oft.The ball falls 20 metres in a time of 2 seconds.The time in seconds) that the ball takes to fall 605 m isa) 10b) 11c) 12d) 13Explain step by step
Answer» c) 11Step-by-step explanation:As mentioned, 'd'is directly PROPORTIONAL to 't^2'.Given d1=20 and t1=2d2=605 and t2=?(20/605)=(22)/(t2t2)(4/121)=4/(t2t2)(4/1214)=1/(t2t2)(1/121)=1/(t2t2)121= t2*t2t2=√121t2=11.
