Question

If a ball is fall down from a height of tower 100m it strike the ground in 10 sec . find the value of G.​

Answer 1

Given the ball drops or fall down from height

hence Initial velocity is 0

So we are given

a) Initial velocity

b)distance

c) time

Hence using 2nd equation of motion

$S=ut+\frac{1}{2}at^{2}$

here

S is the distance(More appropriately displacement ) covered

u is initial velocity

a is the acceleration due to gravity =?

t is the time

$S=ut+\frac{1}{2}at^{2}\\100=0(10)+\frac{1}{2}\times a\times (10)^{2}\\100=0+\frac{1}{2}\times a \times 100\\100=50a\\a=2m/s^{2}$

Hey mate there must be some Glitch in your question as value of gravity is very less , which is uncommon

anyway Hope it helps
