The falling height of an object is proportional to the square of the time. One object falls 64 cm in 2 sec then in 6 sec from how much height the object will fall ?
A. 192 cm
B. 276 cm
C. 436 cm
D. 576 cm
Answer: Option D
Solution(By Examveda Team)
h α t2⇒ h = kt2 for some constant k
⇒ 64 = k × 22 = 4k
⇒ k = 16.
Let the required height be x cm.
Then,
= x = 16 × 62 = (16 × 36) cm = 576 cm.
