Question

a stone is allowed to fall from the top of tower of 50 m height calculate time and velocity taken by stone to meet the earth.​

Answer 1

velocity

v2 - u2 =2gh

v2 - (0)2=2×10×50

v2= 1000

v=10 root 10

time

v= u+ gt

10 root 10 = 0+10×t

10 root 10 = 10 t

time = root 10

Answer 2

hlo mate

Given,

H=50m

g=9.8m/sec

We have a formula i.e,

T^2=2H/g

T^2=2×50/9.8

T^2=1000/98

T=(10×5^1/2÷7)sec

T=u/g

u=T×g

u=(14×(5)^1/2)m/sec
